![]() Average terminal velocity is 193kmph (120 mph) in a face-down and arms stretched position. When the drag force cancels the acceleration due to gravity and the net acceleration decreases to zero, at that time the diver is moving at zero acceleration or terminal velocity. Previous text: When the drag force decreases the acceleration due to gravity to almost zero, at that time the diver is moving at zero acceleration or terminal velocity. The drag force, caused by the air resistance, creates an acceleration in the opposite direction to the acceleration due to gravity and this continues until the net acceleration is zero.Įditor’s Note: Thanks to reddit user /u/Bozmancc for the correction. Previous text: The drag force, caused by the air resistance, opposes the pull due to gravity and decreases the acceleration. ![]() The GravityĪs soon as the sky-diver jump out of the plane the acceleration due to gravity pulls him down at 9.8m/s 2.Įditor’s Note: Thanks to reddit user /u/Bozmancc for the correction. Lets see what forces are actually acting on the skydiver when he jumps from the plane. If we take an example of a skydiver, we would learn that a heavy skydiver would fall faster than a lighter one. Remember that free-fall does not consider air resistance or any other drag force which actually exist in the real world. From the beginning we are taught the classical physics lesson that objects of different mass fall at the same rate towards the ground, a classical example of free-fall.
