Skydiving: falling with constant velocity
... equals the weight, the forces cancel, and the skydiver then falls with constant velocity called the “terminal velocity.” • Without a parachute, a skydiver’s terminal speed will be greater than about 100 mph (not good for landing!) • The parachute increases the air resistance and reduces the terminal ...
