How can the effect of catching a slow, heavy object be the same as catching a fast, lightweight object?
They have the same momentum.
Momentum is defined as? (formula)
Mass times the velocity.
How many types of COLLISIONS?
3 types
What type(s) of collision that KE is not conserved?
Inelastic and Perfectly Inelastic Collision
KE converted into what in INELASTIC COLLISION?
Sound, thermal energy, and can change shape.
What type of collision of this picture?
Perfectly Inelastic Collision.
After the two American football players collide they will stick together or bounce away?
Stick together
This is formula of what?
Elastic Collision
The law of conservation of momentum states what?
Momentum is conserved. p before is the same as p after.
What type of a collision where momentum is conserved, KE is not conserved, and the objects bounce off each other?
Inelastic Collision
The momentum conserved in which collision?
Inelastic, elastic, and perfectly inelastic
Mary noticed a collision outside the coffee shop where two cars collided and stuck together. What type of collision did Mary observe?
Perfectly Inelastic Collision

0.1 kg-m/s
Momentum is a what quantity?
Vector quantity
If 2 objects collide and stick together, what will happen to their velocities?
Velocities will decrease
What are the units for momentum?
kg*m/s
