Question

In a system when two objects collide momentum is conserved if

Answer 1

In a system when two objects collide momentum is conserved as (collision)

Answer 2

In a system when two objects collide momentum is conserved if total momentum remains equal before and after the collision.

This can be explained in the following way:

• The above statement denotes the law of conservation of momentum, according to physics' rules of conservation.
• Any object's momentum is determined by its mass and velocity. Because velocity is a vector quantity with both direction and magnitude, momentum is also a vector quantity.
• When an object A with mass m₁ moves with velocity v₁ in one direction and collides with a static object B with mass m₂, object A loses momentum to object B, which causes it to move with velocity v₂.
• The transfer of momentum occurs throughout the process owing to collision, and momentum is considered to be constant.
• It can be given as: p(momentum) = m₁ Δv₁ = -m₂ Δv₂
• Hence, law of conservation of momentum is stated.
