When a sky diver free-falls through the air, the process is
A) nonspontaneous because he is accelerating due to the force applied by gravity.
B) nonspontaneous because he is losing potential energy.
C) nonspontaneous because he had planned the jump for two weeks.
D) spontaneous.
E) in equilibrium.

Question

Quizplus · Accepted Answer

The free-fall of a skydiver is a spontaneous process because it occurs without the need for any external force or intervention once the jump is initiated. The force of gravity is the only force acting on the skydiver during free-fall, and it causes the acceleration of the skydiver towards the Earth. This acceleration and loss of potential energy are natural occurrences dictated by the laws of physics, and do not require any external intervention to occur.
