Question

Does a man standing at rest on a moving track posses K.E ?

Answer 1

Answer:yes

Explanation:because kinetic energy is possessed with virtue of motion and the man is in motion with respect to the moving track

Answer 2

Answer:

Yes

Explanation:

$\underline{\underline{\bold{\mathfrak{Terms\:to\:know}}}}$:—

Kinetic energy:

⏩ It the energy which a body gains when it is in motion.

Potential energy:

⏩It is the energy which is gained by an object's position relative to other objects.

⏩Potential energy is associated with restoring forces.

$\underline{\underline{\bold{\mathfrak{Reason:}}}}$:—

◽When the man stands on the moving track it becomes the part of the track itself as a whole single body.

◾The track is moving so its in motion as it changes its position with reference to an fixed point maybe in 3 dimensional Surrounding, it posses kinetic energy.

◽Now as the Man is in contact with the track he too will Posse's kinetic energy as he himself moves with the track.

◾But according to a person who is on the track that man will possesses no kinetic energy unless he is walks on the track.

◽Energy is a property of an entire system its not just of a part.

◾When we take the whole system in Consideration, then the energy is conserved and is independent of the frame.
