Conservation of Momentum - Collisions

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before a collision is equal to the total momentum after the collision.

Front

What happens to momentum in elastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved.

Front

What happens to momentum in inelastic collisions?

Back

In inelastic collisions, momentum is conserved, but kinetic energy is not.

Front

What is the formula for calculating momentum?

Back

Front

If two objects collide and stick together, what type of collision is it?

Back

It is an inelastic collision.

Front

What is the final velocity of two objects that stick together after a collision?

Back

The final velocity can be calculated using the conservation of momentum formula.

Front

In a two-body collision, which quantity is always conserved?

Back

Momentum is always conserved.

Front

What is the effect of mass on momentum?

Back

An increase in mass will increase momentum if velocity remains constant.

Front

How do you determine the direction of momentum?

Back

The direction of momentum is the same as the direction of the object's velocity.
