Question

A car is accelerated on a leveled road and attains a velocity 4 times of its initial velocity. In this process the potential energy of the car

• A. does not change
• B. becomes twice to that of initial
• C. becomes 4 times that of initial
• D. becomes 16 times that of initial

Answer 1

The correct option is A does not change

Potential energy is the energy possessed by a body by the virtue of its height from the ground and in the given case, the car only increases its velocity 4 times but its height from the ground remains constant. Thus, the potential energy does not change.
