Question

Which physical quantity remains constanta. in an elastic collisionb. in an inelastic collision

Answer 1

Hii dear,
You forgot to mention quantities.
I think you want to ask about momentum, total energy and kinetic energy.

◆ In elastic collision-
a) Momentum - constant
b) Total energy- constant
c) Kinetic energy - constant

◆ In inelastic collision-
a) Momentum - constant
b) Total energy- constant
c) Kinetic energy - decreases as it is converted to heat and sound.


Hope this helps you...

Answer 2

HLO MATE HERE U GO

⭐. The total momentum and total K.E of the system remain constant in elastic collision.

⭐. The total momentum of the system only remains constant in an inelastic collision.
