Answer 1

Answer:

Collision:-)

When two or more bodies interact for very small interval of time due to internal forces only, as a result of which velocities of the body is changed, collision is said to be a occurred .

☆NOTE"----

Since there are no external forces are involved in collision hence Momentum before collision is always equal to the momentum after the collision.

ln collision kinetic energy May or may not be conserved.

Answer 2

Answer:

Collision is short-duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this. Collisions involve forces (there is a change in velocity).
