Question

A car is accelerated on a levelled road and it attains a
velocity 4 times of its initial velocity, in this process the
potential energy of the car
(1)
a) does not change
b) becomes twice of its initial value
c) become 4 times of its initial value
d) become 16 times of its initial value​

Answer 1

Answer:

does not change

Explanation:

becouse in accelerated object potential energy is absent

Answer 2

Option (a) is the correct answer that is potential energy does not change

Explanation:

• Potential energy of any body is the energy possessed by change in its position or configuration of the body. For example when a body is raised up to an height then is store energy in it as potential energy, if a spring is stretched its configuration gets changed hence it also store energy in it as potential energy
• In the given example, car's velocity is changed that is change in motion occurs but there is no significance about the change in position or shape or configuration so its kinetic energy changes and not the potential energy, hence option (a) is the correct answer
