If two balls collide in air while moving vertically, then momentum of the sytem is conserved because

gravity does not affect the momentum of the system

force of gravity is very less compared to the impulsive force

impulsive force is very less than the gravity

gravity is not acting during collision

Assertion: Collisionn between two billiard's ball are inelastic Reason: Momentum remains conserve during the collision.

A ball of mass moving with constant velocity u collides with a smooth horizontal surface at O as shown in Fig. Neglect gravity and friction. The y -axis is drawn normal to the horizontal surface at the point of impact O and x -axis is horizontal as shown. About which point will the angular momentum of ball be conserved?

STATEMENT-1 : In an elastic collision between two balls, the total kinetic energy of the two bodies does not remain conserved during the collision. and STATEMENT-2 : As the balls collide, they compress each other.
