Question
A car is accelerated on a levelled road and acquires a velocity 4 times of its initial velocity. During this process, the potential energy of the car :
Options
does not change
becomes twice that of initial potential energy
becomes 4 times that of initial potential energy
becomes 16 times that of initial potential energy

Solution
Potential energy of an object depends only on its position above the ground and mass.. So, the potential energy of a car traveling on a levelled road does not change.
Therefore, the answer is,
(a) does not change
