Question

when a match box from the floor and put it on a almiral the potential energy of the box increases but there is no change in its kenitic energy? explain

Answer 1

well I guess the answer could be that potential energy is the energy store by the virtue of configuration and position I. e. mgh whereas kinetic energy is possesed when body acquires some velocity. in this case only change in position is there but the body is still at rest hence no kinetic energy shall b there

Answer 2

here there is no change in kinetic energy because there is no velocity gained
