Which energy transformation occurs after a skydiver reaches terminal velocity?

Question

Gravitational potential energy transforms into thermal energy.
Gravitational potential energy transforms into kinetic energy.
Kinetic energy transforms into thermal energy.
Kinetic energy transforms into gravitational potential energy.

Answer 1

After a skydiver reaches terminal velocity, the correct energy transformation is:

Kinetic energy transforms into thermal energy.

At terminal velocity, the forces of gravity and air resistance are balanced, so the skydiver no longer accelerates. While falling at this constant speed, the kinetic energy remains constant, but some of it is converted into thermal energy due to air resistance (drag), resulting in heating up of the air and the skydiver.
