How does weight, gravity and air resistance affect a skydiver?
Weight doesn’t. Weight is an affect of gravity. If you mean mass, that’s only slightly different in that you have inertia. Gravity sucks – so a skydiver goes down. Air resists gravity’s best effort to get you down. In free fall your maximum speed is roughly 111MPH – commonly refered to as “terminal velocity” – and without a ‘chute it will be. Gravity speeds you up; air resistance slows you down. Weight isn’t involved until the ‘chute opens then you have to deal with your inertia.
