physics question 7

Answer 1

Can you explain me the differnece in elastic and inelastic , I m confused doing this qestion

Answer 2

Elastic is like a rubber band. It will stretch then return to it's original state. Something that isn't elastic will not return to it's original state, rather it will deform/elongate.

Answer 3

Elastic collision means kinetic energy is conserved.

Inelastic means KE is not conserved (some is turned into heat/sound etc).

You can check to see if:
KE before collision = KE after collision

Answer 4

The fact that it comes to a stop, should give you a hint as to whether or not KE was conserved.

Answer 5

Elastic collision is a collision in which the both total momentum and kinetic energy of the system remain conserved during the collision.but in case inelastic collision total momentum remains conserve but there is a loss of kinetic energy. So Basic difference between the both is that in case of elastic collision KE remain conserve but in inelastic collision there is a loss of KE.
