In what type of collisions, momentum is conserved?

• Inelastic Collisions

• Elastic and Inelastic Collisions

• Elastic Collisions

• None

In what type of collisions, are momentum, mechanical energy, and kinetic energy is conserved?

• Head- On Collisions

• Inelastic Collisions

• Elastic Collisions

• Heavy Collisions

The difference between inelastic and perfectly inelastic collisions is that...

• In one type of collisions, objects stick after colliding, while the other objects bounce,and move separately.

• One type maintains Kinetic Energy, while the other doesn't.

• One type maintains velocity, while the other doesn't.

• One type maintains momentum, while the other doesn't.
