Question 2
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

(a) does not change

Since potential energy depends on the change in the height of the body from the ground. Since the height of the car from the ground does not change, hence potential energy remains constant
