Question

During a race, you run on a leveled track accelerating and acquire a velocity 3 times your initial velocity. What would be the change in your potential energy?

• A. It does not change.
• B. It becomes 1.5 times that of your initial potential energy.
• C. It becomes 3 times that of your initial potential energy.
• D. It becomes 9 times that of your initial potential energy.

Answer 1

The correct option is A

It does not change.

Potential Energy is mathematically represented by the formula P.E = m $\times$ g $\times$ h, where m is the mass, g is acceleration due to gravity and h is the height in meters. As you are running on a leveled track, there is no change in potential energy because there is no change in the height of the body from the ground.
