Question

As a sky diver gains speed while in freefall,

Group of answer choices

A. potential energy is being converted into kinetic energy

B. kinetic energy is being converted into potential energy

C. potential energy remains constant as the kinetic energy increases

D. kinetic energy remains constant as the potential energy increases

Answer 1

When a skydrive drive,at initial position of driving the driver should be at rest i.e, initial velocity u=0.let us assume the drive drive from a height H and gain a velocity v_{​​​​​​0}​​​ when it reaches the ground. And v and h be the velocity and height at any time instant.g is the acceleration due to gravity.

Let's draw a diagram

According to diagram at point A:

• Kinetic energy
• Potential energy
• Total energy

At point B:

• Kinetic energy
• Potential energy
• Total energy

At point C:

• Kinetic energy
• Potential energy
• Total energy​​​​​​​

So from the above data we can conclude that with the decrease in height the velocity of the driver increases and thus the potential energy is converted into Kinetic energy.

As,at point A there is only potential energy and at point B there is a decrease in potential energy and increase in Kinetic energy,and at point C there is no potential energy only Kinetic energy.thus all the potential energy is converted into Kinetic energy.

Ans(A) is correct
