I see that this thread diverged a bit, but thanks for the reply, which put it back in focus! I have now mostly decided on which math electives to take based on the helpful responses above. I tried to convey that I would indeed have many upper-level physics and few math courses left, but they...

No problem at all!

Yep: PHYS 438 Zoological Physics Animal systems viewed from a physicist's perspective. Topics include sensory systems, energy budgets, locomotion, internal flows, physical advantages of grouping.

Thanks for the responses. I now have a general idea of the math electives. Since I am already taking most of the physics upper-level courses other than some bio/ medical/ zoological physics and some application/ experiment, the math electives are the only courses that are somewhat related to...

I am a second-year combined honour in physics and math with prerequisites for 4th-year math courses. I am hoping for a direct entry (if possible) into a top US PhD physics program in quantum with a current unofficial cGPA of 3.9/4 (88%). Since I am in Canada, we only have percentage grades that...

free fall

For example, if a ball is from a certain height, the work done is 0 as there is no change in total energy the Ef =Ei. However, there is a constant force applied over a certain distance, suggesting work is being done. Which aspect am I forgetting/missing? Or is it that the definition of work done...

When a coin is dropped from a certain height and collides with a glass surface, is the majority of the potential energy converted to sound or heat? And how would one determine this as I only hear the sound and cannot measure the significant change in temperature?

Thanks for the response, but I don't quite understand the difference between modes of oscillation and harmonics of oscillation. Could you dumb it down a bit for me?

In the popular answer for the coin-mass question of Physics Stack Exchange, I am wondering what are the correlation between the first red peak at around 9kHz and the second red peak at 16kHz. I first thought that they are consecutive harmonics but there was no way of proving it as I do not know...
