A car starts moving on a level road with an acceleration of 5 m/s²for 10 seconds, what will happen to the potential energy of the car?

Answer

Correct Answer : c ) It will remain the same

The potential energy does not depend on the velocity. Moreover, the road is leveled so there will be no change in the height of the road. So, it is safe to say that the potential energy of the car shall remain unaffected. However, Kinetic energy will increase with speed.
