Question by pinkknot401: What science fair project can I do that involves cheerleading?
I am in 8th grade and want to do my science fair project on something to do with cheerleading but can’t think of anything. HELP!!!!!!!!!!

Do the physics of cheerleading. You know, tumbling & stunting. The physics of tumbling and stunting.

Give your answer to this question below!
Building on Ellie’s idea, you can pick a stunt and calculate stuff about it.
ex. Lib Scale
Calculate the height from the ground, the flyer’s mass then you can use the equation: Potential Energy = mass*gravity*height
gravity = 9.80m/s^2
Then, on the ground, get the flyer to pull a scale and see how high it is from her ground to her foot. that way, you can see how much speed she will gain from dropping it. (potential energy when her foot is in the air is equal to kinetic energy when her foot has dropped)
ex.
Potential Energy = mass*gravity*height and Kinetic Energy = 0.5*mass*velocity^2.
That way, the height -> put the flyer on the ground, measure the height from the ground to her foot in scale. Then, the mass is the wieght of the flyer (in kilograms!) and the velocity^2 is her speed squared.
plug in ex: (75Kg*9.80*1meter)/(0.5*75)= velocity squared.
Square root your answer, and you will get the speed she gains from dropping her foot! The thing is, the masses cancel out, so ANY flyer who can get her foot to that height will get the same velocity when they drop their foot.
Note: all things drop at the same rate — see Newton’s laws. Everything will accelerate downwards at -9.80m/s^2
