Solution
If we increase the velocity of a car moving on a flat surface to four times its original speed, its potential energy will not change.
Explanation:
The energy stored in an object because of its specific state or position is called its potential energy. The potential energy is expressed by the following formula (P.E.) = mgh. That is, the potential energy of an object does not depend on its velocity, but on its height above the ground.
