Momentum

The momentum of an object depends upon the object's ___________&_____________.  

• size and shape
• mass and speed
• mass and veloctiy
• mass and energy

The equation to calculate momentum is

• p=mv
• p=1/2mv²
• p=mgh
• p=mg

Momentum is a ____________________ quantity

• science
• scalar
• vector
• energy

Which of the following has the least amount of momentum?

• An ant walking along the ground
• An ant at rest
• An elephant walking
• An elephant running

What is the unit for mass?

• m/sec
• kg/sec
• kg
• kg m/sec

An object with a mass of 2000 kg at rest has what momentum?

• 2000 kg m/sec
• 0 kg m/sec
• 2000 kg
• 2000 m/sec

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

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

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
• Explosive
• Elastic

While playing pool, Emma notices that the pool balls bounce apart.  What type of collision is this?

• Elastic
• Inelastic
• Explosive
• Force

In any collision (crash) the ______ is ALWAYS constant

• Total Momentum
• total speed
• total Velocity
• Energy
