Airtime Trampoline

Hey, me and my brother are having a contest on who can jump on a trampoline and can get the most airtime of a rebound. I'm about 11 Stone and is about 5 stone, he said that the weight will make a difference, but it? As he cannot jump higher but it is lighter so if it catch up at the closing?

For the calendar, we record the jumps and counting frames.

Please explain this test is fair.

There is no question of you has a greater mass, as time goes flying. The equations are of the same movement and free fall (or parabolic) over the shorter of a distance you are traveling less and so slow speed that you travel has no weight in the calculations.

What matters with your weight, however, with the trampoline is that you may be able to use your weight to stretch over the trampoline, or store energy over it due to gravity. This energy is then transmitted to you, and if you have more energy up front, you can get more speed at the initial rise, which will make your travel time in the air longer.

OK lets just start with the basic idea of EHV is NOT matter wat the weight of the object is, the rate of acceleration of the fall will be the same. Your brother will be held from u because you can exert more strength to jump higher. and fall wouldnt be a problem because ull both fall at the same pace. the air resistance will not do much to change the results. win, so overall ull if u can exert more force. =]

gravity is the same on both you and your brother if gravity is correct
weight is not the problem .... what counts is the strength of your calf muscles (muscles of the leg) to push your weight against jumping on the trampoline!

hope you ^ _ ^

The weight is irrelevant in this situation. Gravity causes both of you to accelerate the reduction of 32 feet per second per second.

Absolutely. Gravity does not depend on your weight.
