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 :

(a) does not change

(b) becomes twice that of initial potential energy

(c) becomes 4 times that of initial potential energy

(d) becomes 16 times that of initial potential energy

Solution

(a) does not change

Potential energy will not change as the road is leveled and the height of the body remains the same, although its speed increases.

So, correct answer is option (a).
