Question

A car is accelerated on a levelled 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

ans

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.

Answer 2

Answer is:- (a) does not change
