100
these two physics quantities are used to calculate momentum

100
These two physics quantities calculate impulse
What is force and time
200
These are the units for momentum
What are kg*m/s
200
This type of collision happens when a ball bounces off of a wall
What is elastic
200
This is why a longer wrench helps with a stuck bolt
What is a longer moment arm (length)?
200
An object which looses it's centripetal force will shoot off in this direction
What is tangentially
200
These are the units for impulse
What are N*s
300
This is what negative momentum means
What is going the opposite direction
300
If two objects collide and stay at rest, what can you say about the momentum of each?
What is balanced, equal but opposite
300

What is no?
300
This force acts as the centripetal force when a motorcycle rides around a round cage
What is normal force
300

What is B
400
This is why momentum is conserved when you drop a weight onto a cart
What are no external horizontal forces
400
This is a collision in reverse

What is no?
500
Suppose superman throws an astroid 100 m/s (in space) which has 2000 times his mass. How fast would superman be thrown backward?
What is 200,000 m/s (still less than 1% the speed of light)
