Physics Video/Photo project ideas

im doing this extra credit project for my physics class, basically we need to take a video or picture of something cool. I was thinking some slow motion video, like time warp (of course i only have an hv30 so i cant slow it that much). Anyone have any ideas?

for slo mo you could do the flex and pop of a ski, like pull the tip back and let it snap, it would be way sicker if it was uber slo mo but hv30 isnt super high speed.

maybe try some time lapse stuff?

slo mo of a some sort of magnet could be cool.
creation of icicles (time lapse), more chemistry though, only gravity does work in this situation.
capturing time dilation would simply be the best, but i'd say it's impossible to capture haha

I've always wanted to to see this comparison.

-Film a friend hitting a jump just straight airing it.
-Then film that same friend, going approximately the same speed, doing a front flip.
-Shoot both from a stationary side angle.

Then compare their trajectories and discuss transfer of center of mass etc.



Should be relatively simple but definitely a good lil' extra project related to skiing.

calculate to coefficient of friction between the base of the ski and a metal rail (assuming you've done mechanics).

just for reference if you want to use it in a calculation, to coefficients of friction of a waxed ski on snow.

Waxed ski on snow...
Kinetic- 0.05
Static- 0.14

You could also do something like the centripetal force of your ski in a spin.

Fc= (m*v*v)/r

What you could do is shoot the slow-mo shot you want in the highest frame rete the HV30 can do, then preform what is called frame interpolation.(A program calculates motion between frames and comes up with an in between frame)
