What is the scince behind skydiving ? The physics behind skydiving involves the interaction between gravity and air resistance. When a skydiverjumps out of a plane he starts accelerating downwards, until he reaches terminal speed. This is the speed at which the drag from air resistance exactly balances the force of gravity pulling him down.

What is the difference between the free fall and skydiving? The difference between the free fall and skydiving is that freefall is to drop in a state of freefall while skydive is to be in freefall after jumping from an aircraft and landing safely by deploying a parachute.

What is terminal velocity ? Terminal velocity is the maximum velocity attainable by an object as it falls through a fluid. It occurs when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the object. Since the net force on the object is zero, the object has zero acceleration.

What is the effect of the shape of the parachute and the air resistance ? The effect of the shape of the parachute and the air resistance is that How large a parachute is affects its air resistance or drag force. The larger the parachute, the greater the drag force. In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall.
