Momentum and Collisions

In this type of collision, objects tend to "stick" together.

• elastic
• inelastic 
• They "stick" together in both types of collisions.

When the velocity of an object is doubled, its momentum _______.

• remains unchanged in accord with the conservation of momentum.
• doubles
• quadruples
• decreases
