Vedclass · Answer

(B) Potential energy $(PE)$ is defined by the formula $PE = mgh$,where $m$ is the mass,$g$ is the acceleration due to gravity,and $h$ is the height of the object from the reference level.Since the car is moving on a levelled road,the height $(h)$ remains constant throughout the motion.Because $m$,$g$,and $h$ do not change,the potential energy of the car remains constant.Therefore,the potential energy does not change.

$A$ 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
