Kinetic energy is conserved __________ collisions.

• only in elastic

• only in inelastic

• in all

• never during

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

• Elastic

• Inelastic

• Completely inelastic

• none

Conservation of momentum means that the initial and final momentum in a collision are

• different

• the same/equal

• impossible to determine

• always the same as the kinetic energy

The total momentum before a collision is _________ the total momentum after a collision.

• equal to 

• less than 

• more than

• It depends on the type of collision

What happens to the total momentum in a perfectly inelastic collision?

• It increases

• It decreases

• It remains the same

• It becomes zero

Which option is NOT likely to occur in a collision? (slide 2)

• The objects change speed.

• Everything stays the same.

• You might hear a sound.

• The objects change shape.
