Sally runs and jumps off of a diving board and lands on a tube (she stays in the tube).  The collision between Sally and the tube is

• Inelastic
• Perfectly Inelastic
• Completely absurd

Two objects of the same mass collide with each other.  The second object is at rest and the first is moving at 5 m/s North before the collision.  After the collision, the first mass is at rest and the second mass continues at 5 m/s North. 
The type of collision represented by these two masses is

• Inelastic
• Completely Inelastic
• Elastic

Bob is moving at a velocity of 3 m/s South when he jumps into a sled that is at rest. The quantities that are conserved during this collision include:

• Kinetic Energy only
• Momentum only
• Momentum and kinetic energy

Rahim observed a collision in lab where the kinetic energy after the collision was equal to the kinetic energy before the collision.  This type of collision is

• Completely Inelastic
• Elastic
• Inelastic

Shaniqua noticed a collision outside the coffee shop where two cars collided and stuck together.  What type of collision did she observe?

• Elastic
• Inelastic
• Completely inelastic

This picture is an example of ____________

• Elastic Collision
• Inelastic collision

The law of conservation of momentum states that the total momentum of all objects interacting with each other will  ________________________ no matter of the nature of the forces between the object.

• increase
• decrease
• remain constant
• fluctuate

What is Newton's Law of Conservation of Momentum?

• Object in motion stays in motion and an object at rest stays at rest unless acted on by a outside force
• Force = mass x acceleration
• For every action there is an equal and opposite reaction
• Momentum can not be created or destroyed without outside forces
