Your videos are a godsend. Thanks for putting your time and effort into these videos. I know you only do them when your not studying or working so it must be difficult at times, so thanks. :)

[brickmatt]

Mate your videos are sick, a lot better than the rest of the competition, i'd love it if you made more xxxx

[SLRNT]

more of these, if just teachers could make math this easy to learn :D great video

[gordonchan]

Sadly, for a = kx to be true, the approximation sin(x) = x is applied.

The real motion is described by a nonlinear second order differential equation, a = ksin(x). Nonlinear correspondences to the presence of the sine function.

This means that there is no any exact solution for the motion of a pendulum and simulations can only provide a numerical solution.

This really helps since I'm going through this in school now.

HELLO MATE. WHAT SOFTWARE do YOU USE TO EDIT YOUR VIDEOS?

[dylanparker]

i honestly didn't realise that's how the amplitude was defined - you've indicated it to be the length of the straight line between highest and lowest point of the pendulum bob in its swing?

who knew? well, apart from you and other physicists!

How does swinging one's leg out on a swing increase resonance? Also I'm not clear on the cos and sin graphs covered at the beginning I was hoping for more breakdown!

[ellendavies]

This is brilliant!! Please could you do a video about space and calculating astronomical distances (cepheid variables, wein's law and parallax distances)

[ProEpicGuyac]

Answer at 1:30 is wrong .. I calculated and the answer was 21.143

*Minutephysics* (ahem)
Good effort tho
