A
When one object exerts a force on another object, that object will exert an equal and opposite force on the first object.
2
Q

Action force and Reaction force
3
Q
What is the action force?
A
the force that applies force on another object
4
Q
What is the reaction force?
A
the force that gives and equal force on the action force in the opposite direction
5
Q
What is the Law of Conservation of Momentum?
A
the momentum in a system is constant without an external force changing the momentum
6
Q
What is an elastic collision?
A
a collision where the momentum in the system does not change
7
Q
What is an inelastic collision?
A
a collision where the momentum in the system changes because of an external force
