This physics video tutorial explains the concept of simple harmonic motion. It focuses on the mass spring system and shows you how to calculate variables such as amplitude, frequency, period, maximum velocity, maximum acceleration, restoring force, spring constant k, elastic potential energy, kinetic energy, and mechanical energy in addition to describing the motion of the mass spring system using a sinusoidal function such as sine or cosine. This video contains plenty of examples and practice problems.

I wanted to share my working just incase if someone confused at 1:50:05 @1:50:05 The question is asking for velocity, acceleration, and restoring force at x = 0.5m We know Vmax = 18.6 m/s and A = 1.5m and set the calculator in radiant mode Method 1 -- By subs x = 0.5m into the formula v(specific time) = Vmax * sqrt(1 - x^2/A^2) This gives V(at x=0.5) = 17.536 m/s Methods 2 -- If we want to use the V(t) equation we have to find the 'time' when the block at x=0.5 Using x(t) = 1.5 * Cos (12.4t), we subs the value 0.5 = 1.5 * Cos (12.4t), this gives t = 0.099271s Thus, subs t = 0.099271s into V(t) gives v(0.099271) = 18.6 Sin (12.4 * 0.099271) = 17.536 m/s (Same answer as Method 1) This has been discussed before in the comment section but I hope I could clarify this again. I also wish someone could correct my working if I made any mistake.

This was a really intimidating topic for me, and the way you taught it made me finally feel like I understand it. Specifically, the way you gradually introduced new stuff. By the time you introduced period and frequency I was confident I could use the energy equation. And by the time you start graphing sines and cosines I'm already blasting trough the frequency problems. Thank you for the time you put into the lesson!

That is so true..he makes me feel like I've learned the topic detail by detail, perfectly. And it's so real..every second. My friends sometimes sarcastically say things related to me being a duller and also lazy because I don't practice because of online friends . It's 10:21 pm, I haven't started studying yet, since 6:30pm. It's very heartbreaking. I can't understand and focus well physically, where there are noisy brats, slow explanation, just all that tension I can't bear and could start to cry anytime soon. The Organic Chemistry Tutor is one of the channels who helps me a lot and provides more interesting information. Very glad!! Hope I'll really become a smart student...I feel devastated, all my school mates called me as topper topper, because I wasn't lazy, wasn't overthinking, was studying consistently. It's the opposite now, and college mates think I'm the worst. I always get the last rank even i can't believe it. Straight A to negative marks student. Very.. devastating. I can do it though. Although it feels like a stab through my heart. I love learning.

It should be 0, this seems to be a mistake. Since x=A, the PE=Total Energy, and KE=0. There is another mistake during the problem at 1:50:00, x=0.5m and he plugs in t=0.5 for the t in the x(t), v(t), and a(t) functions. You need to solve for t, then plug that number in. I think the correct answer is, at x=0.5m, v= -17.54 m/s and restoring Force = -42.28 N.

This video perfectly shows the frustrating part of physics. There is near zero convention for symbols. f can be frequency, unless it's friction. V can be frequency unless you're using f. And if you're not speaking English then presumably a different letter could be friction. KE can be kenetic energy but k can also be a constant in Hookes formula which can be written with or without the negative sign depending on your mood. w can be work unless it's actually a lower case omega. And on and on. How have we not called a meeting and set some damn standards? Any idea on how many people could potentially be contributing to physics but aren't because they give up the first quarter? Absolutely ridiculous.

@stroob3734 5 жыл бұрын

The fact you wrote this means you don't understand physics at all. f is frequency and not friction because there's no friction at play here since none of his problems have them and if you took this class you wouldn't deal with friction anyway (maybe a few problems bring it up so you don't forget about the real world, but most of these problems test your understanding of the topics and equations and not about friction). Even if there was friction you can literally write: Friction = [Insert variables and relationships here]. "KE can be kenetic energy but k can also be a constant in Hookes formula" what are you even saying here KE and k are different in spelling. And the sign of k does not depend on your mood but how you set up your problem and axes. There's also a clear difference between W and ω... if you can't differentiate between the letters of the Greek and English alphabet then there's no hope.

I have a problem with the problem done at 1:49:51, part b. We are asked for the velocity and acceleration at x=0.5, which from what I understand, is displacement. The equations for x, v, and a, are written as functions of time, yet we substituted the x= 0.5 where we should be substituting t=?(something)... were we not supposed to use the equation of x to solve for t first, then substitute the t that we get onto the other equations to get v and a? This is the only issue I have; may I please get clarity if possible?

I was also thinking the same I think you should find the value of t (I found it 5.687) at x=0.5 by using the displacement equation given by the question then you place that t value on the functions we have derived
