Impulse and Momentum

As much as we frequently misuse scientific words in common language, we do have a reasonable grasp of the word momentum. But that's no reason to gloss over this concept, we have to know all the definitions and equations there are! The same goes for the concept of impulse. Check this one out, there are trampolines and baseball.

This was an exceptional video, so big thanks for that. I've studied physics for a good time in highschool, and I thought I was really good at it. Until I got to a CS college and started to study calculus and how it is related to mechanics. Then things got a bit messy and now I am recovering the stuff I thought was self-explanatory at first. I think it was the video I needed to clarify the confusedness in my head. Keep up the great work!

Amm, ok what about the diff btw the impulse and the momentum? it’s not really clear

@carultch 2 жыл бұрын

@@exothermic4549 Impulse is the cause, momentum is the effect. The net impulse acting upon a body equals its change in momentum. Impulse is the time-integral of a force. Net impulse is the time-integral of the net force. Look up what integration means as a Calculus term. The short answer is that it is a multiplication of force and very small time intervals, added up throughout the time interval. Momentum is what a body possesses in motion, which is a product of its inertia and velocity, that is used for keeping track of Newton's third law as a conservation of momentum law.

If you have a force sensor, which is at the end of a track, where an object of mass m slides down, and compare it to an ideal spring replaced in the same spot, would there be any change in impulse if you repeated it? Im so confused, thanks for your help!

@cockroach7237 3 жыл бұрын

The the initial mass of a body is = m1 The mass of the body changes to m2 At time t (the change occurs suddenly, as if m1 - m2 Was dropped on m1 at t ) V2 = m1V1 / m2 According to conservation of Linear momentum m1V1 = m2V2 But according to conservation of kinetic energy ½ m1V^21=½ m2V^22 V2 = V1_/m2 / m2 But velocity cannot be different.. So is one of the principals not applicable in here?

For example in this tutorials comprehension was both the sides divided by -200? Is it done algebraicly ? And should i learn algebra to be able to solve efficiency and how far should i study in algebra to solve physics problems? Is calculus needed to solve physics problems? Please can some answer this questions. It will be really helpfull.

It rebounds with a velocity of 10ms^-1. Calculate the average force of the impact. Can someone help me out? I don’t know whether this is equal to -320 or 160N because I’m a little unsure of whether the final velocity is -10ms as it’s rebounding but yeah. It equals 160N when v = 10ms and -320N when v = -10ms
