What energy transformation occurs when a skydiver first jumps from a plane

gravitational potential energy transforms into kinetic energy.

gravitational potential energy transforms into thermal energy.

kinetic energy transforms into gravitational potential energy.

thermal energy transforms into gravitational potential energy

The skydiver jumping from a plane high up in the sky would most likely experience various energy transformation. For starters, it would undergo a very large gravitational potential energy because of its much higher elevation. After jumping, this energy would eventually transform to kinetic energy due to the force exerted by the gravity.
