What happens when 2 objects moving in the same direction collide?

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).

What are the conditions of elastic collision?

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved in an elastic collision.

Which of the following are collisions in which objects rebound with the same speed as they had prior to the collision?

Collisions in which objects rebound with the same speed (and thus, the same momentum and kinetic energy) as they had prior to the collision are known as elastic collisions. In general, elastic collisions are characterized by a large velocity change, a large momentum change, a large impulse, and a large force.

Does elastic collision cause a rebound?

Suppose a vehicle collides elastically with another object. The vehicle will necessarily rebound. The change in momentum as the vehicle rebounds is greater than in an equivalent inelastic collision. The force on an occupant is therefore greater and that is clearly worse for the occupant.

What does elastic collision in two dimensions mean?

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same. A useful special case of elastic collision is when the two bodies have equal mass, in which case they will simply exchange their momenta.

When two objects collide the total momentum before collision is to the total momentum after collision?

When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It is true for all collisions.

What is the difference between an elastic collision and a completely inelastic collision?

A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.

What is meant by an elastic collision?

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.
