Jackson is actually right about the cars rolling downhill. Source: I have a physics degree. Explanation: If we were talking about blocks sliding down a slope with no friction, Peter would be right. They would have the same acceleration (a = F/m) because the force (gravity) is proportional to the mass. You can also think in terms of energy conservation. The initial energy is mgh, and the final energy is 1/2mv^2, so the mass cancels out and the speed is always equal. However, cars have wheels, and that turns out to be really important in this problem. Some of the energy that the cars started with will go into spinning the wheels instead of moving the car forward. This amount of energy is the same for both cars at a given speed, assuming the wheels are identical. Since the heavier car starts with more energy (mgh is bigger), the energy taken to spin the wheels is a smaller fraction of its total energy. So the ratio of its translational kinetic energy to its mass is higher, and it moves faster. Air resistance plays no role as long as the cars are the same shape and size. I think Mark Rober has a good video about this in regard to Pinewood Derby racing. I'll add that considering two cars racing on a flat surface with identical engines is a different matter, and in this case the heavier car would be slower. It would have a lower acceleration because it has more mass while the force from the engine is the same, and it would also have a lower top speed because of friction in the axels.

Underdogs: Come for the memes, stay for listening to 4 dudes misunderstand physics

Underdogs: There isn't anything after death. Also Underdogs: What is snow?

Jackson is always right. Normally I'd go for Peter, but he's Left handed

Peter shouldn’t argue with Jordan. He got a 76% on his maths test

The fact that some of you have never seen snow blows my mind considering it snows for about 4-6 months of the year where I live.

I gotta say… I’m disappointed in little z. I can’t even trust him anymore. A Mario kart 8 deluxe video without the bone rattler, such a shame.

Funny thing: Kojima went up to Sakurai during Melee and directly asked him to put in Snake, it was too late in development, so Sakurai promised Kojima Snake would get in Brawl Edit: Also funny, Sakurai wanted Arms in Smash Ultimate but they ran out of time, and the Arms director asked him to put in Min-Min, so yeah basically what they said was true

The fact that Peter always thinks he's right when 97% of the time he's absolutely wrong kills me. He's so confidently and cockily wrong too

I swear to god if Cogger doesn't get his lemon...

Having a pill instead of eating a meal seems pretty optimal

Poppt wins the cup: Wait, that’s illegal

The "she goes from another school" joke was so spot on man, the Underdogs have such a good sense of humour together.

Ignoring friction and air resistance, two cars of different mass going down a slope would accelerate at the same rate. Despite the force of gravity(weight) W=mg being stronger on the heavier car (what Jordan says, and is correct about), the acceleration on the two cars would still be the same due to Newton’s second law F=ma (what Peter says, and is also correct about). The only factor on the acceleration of the car is hence the steepness of the slope as the mass of the car cancels out in the calculations. Also Jackson is the funniest underdog :)

The absolutely unrelated intros are such a staple of the series. Love em

The intro really brought out the whole Australia is an atheist nation energy.

jackson missed the greatest opportunity for a "holden these nuts" he's ever had in his life

Damn why isn’t nobody talking about Little z’s triple green shell snipe in 2:53? That was actually so sick

So glad the Underdogs have good taste in drops

Hot take: Jackson is the hottest underdog as well as being the most chill

2:55 Little Z hit every green shell: ultimate skill level achieved

MARIO KART! What one is it? 8 DELUXE!!

Hopcat being so confidently wrong about the speed thing was amazing

Lol I was just sitting here and wondering when the next one is coming out and here it is letsssss goooooooo

Director cogger giving his film expertise FINALLY. Been waiting AGES

13:21 I’m sad that cogger was the only one who thought to say “king poo”

Jordan: I don’t like snow. Canadians: You have been sentenced to 20 years in the maple and moose farm.

I always love all the random conversations when the Underdogs play a Mario Kart game.

When Jackson said you could use the C-stick to accelerate, I paused the video, fired up my switch, loaded in MK8 Deluxe and tried it out. Turns out, you can indeed use the c-stick to accelerate, and also reverse. I was surprised, to say the least.

Whoever incepted Bowser Jr into Sakurai's mind for smash: we need to talk

My high school physics teacher would die if he heard the last conversation

Jackson's right, because he's the funniest, and it's not possible to be a successful comedian and be stupid at the same time.

I would love to see underdogs all taking a physics exam. I’m not too interested in what score they get but more how they get to their answers and the arguments

As someone that lives in Michigan it’s always startling to remember that the majority of the world doesn’t get snow

I love existential Mario Kart. My favourite character is “Why-Guy” Cephalopods is the term they were looking for and corvids (crows, ravens etc) are probably the smartest of the birds given that they use tools of their environment for food and can hold grudges.

"There will be a resultant force which will be proportional to the mass of the object. Hence an object with greater mass feels greater force than the other one. So even if the slope is same for both objects, a massive object moves faster through the slope than a less mass object." -google

Alt title: Jordan arguing with every other Underdog over knowledge you'd know in school.

Hopcat is correct in a world where the there is no air resistance or friction and the cars just side down the hill. But in a real world case where there is air resistance and the cars are rolling Popit is correct. Look at pinewood derby cars. The fastest car down hill is the heaviest car with the lightest wheals.

Zack's 'you guys knew I can drive a truck?' has become the old Jordan's 'you guys knew I played basketball?'

Living in Buffalo, where everyone thinks it shows 24/7, which it doesn't, I still forget how much of the world doesn't get snow

Yay! Another Mario kart video, I've been waiting for this!

As a Canadian, it’s still blows my mind that some people have never seen snow

i like how zach uses the meta kart combo in friendly mariokart matches. what a tryhard

Man I was just looking for a video to watch at work since I watched all my new videos already. Perfectly timed this blessing of a video to me, thank you have a good day

Scary monsters and nice sprites is "YES OH MY GOD" the one you're thinking of with "Dr-dr-dr-dr-drop the bass" is Cinema. Sorry to be that guy, but I'm passionate about this stuff

Them talking about not getting movies and all that gave me fucking ptsd from when someone said I didn't get big bang theory. That was certainly one of the weirdest hills to die on lmao.

i’ve always found that for art, it’s not so much about logic puzzling out what the piece ‘is about’ but rather reflecting on how it made you feel. i think people get stuck trying to crack the code and overthink it (i hear this a lot about poetry), but art doesn’t have answers.

When you’re already very high, sitting here, and you decide to watch an underdogs video....and then they start it like that

Cogger is the best person to do the intro’s, change my mind

the intro literally made me question stuff more than school. forget just Jordan, every underdog should become a teacher cause they did a better job

Little Z shouting Kill me while a blue shell is about to hit him while he crosses the finish line was hilarious 😂

I love your guys Mario Kart videos, they're the best, thanks for the great content

I didnt need an existential crisis rn

I'm with Jordan, I'm not about Toy Story 4. That one doesn't exist. TS3 was a perfect ending.

2:33 them talking about wether they've seen snow hit different. As a swiss that spends the winter months in the mountains skiing since I was like 3 years old, I can't grasp the concept of people in their mid 20s not having seen snow.

Pov: you've already seen the video but watch it again in hopes of Cogger winning

Ah yes, the most important existential question: Do heavier cars roll faster?

When I was taking driver's ed, one of the tutors said I was a very good driver, and I said "It's because I play Mario Kart" and he said another kid had said the same thing to him earlier that day. So it's not driving that makes you good at Mario Kart, but rather Mario Kart makes you good at driving.

Thanks for always uploading funny and entertaining videos Underdogs, today has been a really bad day but you guys can always cheer me up at least a little bit

I liked the chill vibe in this one, nice break from the usual craziness

Last time I was this early making best characters jokes were actually funny

Gonna be honest, Peter's 100% right about the car acceleration thing. No matter how heavy an object is (ignoring rind resistance), it accelerates at 9.81 m/s^2. This is because the force exerted on an object due to gravity is directly proportional to its mass, but the acceleration of an object due to a force is directly proportional to 1/(mass). This cancels out, so all acceleration is the same.

My god Jackson is a blessing on earth

Jordan: I hate food. Also Jordan: Food would be HYPE.

Is the podcast canceled

3:24 I've watched this part like 10 times, and it gets funnier every time

From an energy perspective, potential energy is mgh and it is entirely converted to kinetic energy 1/2mv^2. At top speed and the bottom of the hill, if the cars start at the same height, mass is cancelled. This is neglecting air resistance or friction. However, friction would be a lot higher on a heavier car, but the rolling resistance to start the cars tires rolling would be overcome quicker on the heavier car, so that may be a little more complicated than necessary. Sometimes it’s a bit counterintuitive, but with some simplifying assumptions, the physics equations help clarify things.

‘as long as were cracking each other’ - Cogger 2021

Jackson:You can use the C stick to Accelerate The Mario Kart 8 Deluxe Wiki: He's got us now boys Give him the lemon he deserves

I’m a goddamn onion

love seeing zack rage at fricking mario kart even when he is in the lead. Everyone is good at the game but looks like hopcat has the best luck. Also love the vids guys

Poppt1 was really popping off in this video

The 26 dislikes are the people who don’t believe in global warming

Actually Peter is right due to the laws of physics, having a bowling ball and a basketball and drop at the same time, will still make it so that both land and get to the ground at the same time, and also the heavier it is, the more force you will need to accelerate and makes the car have less acceleration but greater velocity, there is your physics

Okay but that double snipe from zack was actually godlike

I love all the Toy Stories! The fourth one at the end made me cry. But the second one is my favorite. Toy Story and HSM are tied for being my favorite Pixar/Disney movie series. But I haven't seen the third one of HSM.

Most (upwards of 70%) iron and steel is recycled because its faster, cheaper, and more efficient. Virgin iron is still made, but usually used to supplement recycled materials. Heavier objects will typically reach a higher top speed than lighter objects, despite accelerating at the same rate. Heavier objects will continue to accelerate past the lighter object's terminal velocity. The size of the objects and the shape is important as it affects the air resistance

peter… physics lesson: with momentum depends on mass and acceleration. the higher the mass, the higher the momentum. so yes, weight has an effect on speed when something is rolling down a hill

Lessss goooo new mario kart vid with the underdogs is always fun

This vid will go down in history: *The Video that Split the Undergods!* excited for the coverage by TRO

These always make the day so much better

These videos are the drug i need in my life.

I have been waiting so long for this great job

8:46 "Have you seen Shallow Hal?"

Cogger 1000% the funniest underdog Edit: Oh god I should’ve waited till the end before liking the video

Going down a ramp is acceleration of gravity at a angle gsin(theta). F=mg and kinetic energy is (K)=Fd as well as 1/2mv^2 so (2mgd)/m square rooted is velocity. Mass cancels out. Also you need to calculate friction which slows heavier objects down faster by reducing their acceleration. SO THE HEAVIER THEY ARE THE SLOWER OR EQUAL THEY SLIDE DOWN A INCLINE. However a larger mass resulted in a larger momentum and larger force which is why is harder to stop them.

My basic high school education of physics is incredibly tilted by the level of understanding these 4 have to show. Its hilarious.

legit my favourite videos on yt

Did not expect to have an existential crisis while watching underdogs play Mario kart

I personally believe we all are right in the Underdogs! I've liked, subscribed, hit the bell, AND commented

They are both kinda right. Becuase weight does help fight against drag to a certain point. So the heavier car would beat the lighter car downhill because it has more inertia. But in a perfect scenario with no drag they would be the same. It also depends on if the heavier car has the same wheels and their tire pressure. If the heavier vehicle presses the tires flatter there is more surface area so more drag. If the angle of the hill is small then this would greatly affect the outcome. If its something like 40 degrees then the effect would me minimal. Basically physics is complicated.

It all comes down to friction. If there's no friction or air resistance all objects will accelerate at the same rate, whether it is freefall or going down an angle. On the other hand you could have a heavy ass truck with rusted axles and a new carbon fibre bicicle, the lighter bike would win, But if you have the most aerodynamically shaped anvil going down an oiled slope vs a paper cube on the same slope, the anvil will go faster due to it's lesser air resistance. No air resistance or any friction and both will be the same speed. So Peter covering his ass with taking out air resistance kinda makes him right.

Dear Poppt1: I too hate food. I discovered Soylent and my life has been greatly improved. No prep, all your nutrition. It's the best.

Little Z really hit all 3 green shells lmao

Heavier objects in a car will have better speed because of how the extra mass effects Inertia

0:37 The vast majority of animals cannot actually comprehend mirrors. They've put mirrors in wild environments to see how the animals react and all of them perceived it as "More Animals" instead of "A Reflection"

As a boy scout who got way into pinewood derby as a cub scout: the heavier car rolls down the hill faster. Sorry Peter

YOUR MARIO KART VIDEOS ARE THE BEST

They accelerate at the same rate in ideal conditions. It is true that all objects fall at the same rate a=(-)9.8 m/s, but that only pertains to objects in free fall. The acceleration of the cars depends on many things like, the slope or friction in the car and on the surface. To calculate an acceleration on a slope in an IDEAL environment (no air resistance etc) you can use: ma= mgsin(x). (Cars mass)(cars acceleration)= (cars mass)(9.8)(sin(angle)). The m’s cancel on both sides because they are the same mass value (the cars weight doesn’t change) so you end up with: a=gsin(x). “x” is the angle of the slope in degrees relative to your chosen axis( usually horizontal), so the acceleration down a slope would be something like (-9.8)(sin(35)) which is 4.19. The important part is that the masses drop completely from the equation to result in the same acceleration. Example: Paper car weighs 0.1kg (0.1)(a)=(0.1)(-9.8)sin(35) a=4.19 Rock car weighs 100kg (100)(a)=(100)(-9.8)sin(35) “a” is still 4.19 You can also look at this through energy. When a object goes down a ramp potential energy gets completely turned into kinetic energy( in Peters described ideal state). The equation for this situation is mgh=1/2mv^2. (All variables are the same as the other equation above and v= velocity and h=height) As the car rolls down the ramp the potential energy (stored energy from the cars height off the level ground) is being changed into kinetic energy ( the cars speed). The height gets exchanged with speed as it rolls down the ramp. You’ll notice that the masses (m) also cancel in this equation as we are comparing the height of one car to the final speed of that same car. Same mass, it drops out. So the paper car that was 0.1kg and that started 2m up will have an equation that looks like this (0.1)(4.19)(2)=(1/2)(0.1)(v)^2 (Using “a” from above) V= 4.09m/s The paper car will be going at a rate of 4.09m/s The rock car that weighs 100kg will have this equation: (100)(4.19)(2)=(1/2)(100)(v)^2 V is also=4.09m/s The two respective cars have the the same proven acceleration and finishing velocity, which means that neither one would be faster.

Finally more Mario Kart
