IB Physics: The Motion Equations of Simple Harmonic Motion

Justifies the motion equations of SHM, explains the relationships between the displacement, velocity and acceleration equations, and solves some sample problems.
Level/Tier 1: $1.99 per month gives you access to a google sheet with a full updated, well organized, linked listing of all the videos and other resources such as notes, worksheets and solution sets.
Level/Tier 2: $4.99 per month gives you access to new videos. The new videos include IB style multiple choice and problem solving questions with full explanations, previews/reviews of the course content, and updates to the video lessons.
"I would just like to say a massive thank you to you for uploading your videos. I started the IB [and]decided to try HL Physics as it seemed interesting. It turned out to be very far from my forté and I was consistently getting 3s and 4s in tests and mock exams. So a few months before the exam period of this year, I began to panic...Then I discovered your channel. For four weeks prior to paper one, I virtually worshipped your videos, and worked along to them in my 'Big Book of Revision.' Last week, I received my results. Incredibly and almost unbelievably, I obtained a 6 in HL Physics. Not only that, but I was 3 marks off a 7."

Still puzzled as to how this channel doesn't have millions of subscribers. This man has single handedly saved generations of IB students. Thank you sir for your help (:

[ruhi]

Absolutely hate this chapter so this was a godsend thank you so much!

[xinruli]

That was so helpful!! I didn't understand this during class but now I got it, thank you so much.

Do you have any patraeon n or anything I can use to donate/support you? Your videos are the reason I'm passing physics so I would love to pay you back <3.

Sir why in the maximum velocity formula (Vo = wXo), you need the maximum displacement if the velocity when the displacement is max is equal to zero?

[jusypdh]

Hi! Not sure if you'll reply since this is really late, but how why is there a negative sign before the max. velocity at 22:21? Isnt the first equation meant to be X=XoSin(wt) instead of X=XoCos(wt)?

Hi Chris, at 14:65, how did you get the equation omega = square root of k/m, would you mind explain to me that?

[mekimify]

Hello sir,
isn't it that the max. acceleration is -2.4 instead 2.4?

[merennuuskamuikkunen]

Hey! at 11:40 how did you get from vector x to xo ?

[josefhlava]

Hello, I have a question that has been bugging me. How do we know that motion is harmonic? Do we have a proof? In all physics this is just assumed. For example pendulum is not harmonic. Is spring and mass harmonic? Why? How do you know?

why is the radius of the circle the amplitude if the radius is never zero but the amplitude is zero at equilibrium?
