Explain the energy transformations during skydiving?
please note: that I need to EXPLAIN!!!
Thank you very much in advance...your help is very much appreciated!! x
Since this is not my area of expertise, I searched Google under the key words "energy transformations during skydiving" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
Don't just copy the material. Express the ideas in your own words. Although this will take more time and effort, you will learn more.
During skydiving, there are several energy transformations taking place. Let's break it down step by step:
1. Potential Energy to Kinetic Energy:
When a skydiver jumps from an aircraft, they possess potential energy due to their height above the ground. As they begin to fall, this potential energy is converted into kinetic energy, which is the energy of motion. The skydiver accelerates as they fall, and their potential energy decreases while their kinetic energy increases.
2. Kinetic Energy to Air Resistance:
As the skydiver gains momentum and speeds up, they experience air resistance, also known as drag. Air resistance acts in the opposite direction to the motion of the skydiver, creating a force that opposes their downward motion. As a result, some of the skydiver's kinetic energy is transferred to the surrounding air molecules. This energy transfer causes the skydiver's speed to gradually decrease over time.
3. Kinetic Energy to Potential Energy:
As the skydiver continues to fall, they eventually deploy their parachute. This action creates a large amount of air resistance, which significantly slows down their descent. The kinetic energy that was previously lost to air resistance starts converting back into potential energy. The skydiver's speed decreases, and they begin to ascend as the parachute creates lift. The conversion from kinetic energy to potential energy allows for a controlled and gradual descent instead of a free fall.
So, in summary, during skydiving, there is an initial conversion of potential energy to kinetic energy as the skydiver jumps. Then, kinetic energy is converted to air resistance due to the drag experienced during the fall. Finally, the kinetic energy is converted back to potential energy when the parachute is deployed, allowing for a controlled descent.
