1. Newton’s Third Law of Motion states that for every ________________________ force, there is an equal and opposite ________________________ force.
Forces __________________ occur in interacting force ________________________.
Interacting force pairs are _____________________ and ________________________
Is the force of the bullet forward equal to the force of the rifle backward? _____________
Are the accelerations equal? Why? (Think of Newton’s 2nd Law)
________________________________________________________________________________________________________________________________________________________________________

2. Interacting Force Pairs
Why don’t force pairs cancel each other out?
Force pairs do not ___________ on the ____________________.
1st object exerts _______________________ force on 2nd object.
2nd object exerts _______________________ force on 1st object (equal in size, opposite in direction).
Equal forces don’t always have ___________________________.
For example, the action force of Earth pulling on an object and causing it to fall is much more obvious than the equal and opposite reaction force of the falling object pulling on Earth.

3. Identifying Interacting Force Pairs
Action Force =
Bowling ball pushes pin left.
What is the reaction force?____________________________________________________________________

4. Identifying Interacting Force Pairs
Action Force =
Enclosed air particles push balloon wall outwards.
What is the reaction force?____________________________________________________________________________________

5. ___________________________ have momentum.
___________________________ is a quantity defined as the product of the _______________ and _______________________ of an object.
momentum = mass x velocity
p = mv
___________________________ have momentum.
For a given velocity, the __________ mass an object has, the greater its momentum is.
Likewise, the __________________ an object is moving, the greater its momentum is.

6. Momentum ______________________ is related to change in momentum.
When you force an object to change its ______________________, you force it to
change its _________________________.
Momentum is ____________________ in collisions.
The Law of Conservation of Momentum states that the _______________________ of momentum in an isolated system is conserved.

7. Momentum is _________________________.
When a moving object hits a second object, some or all of the momentum of the ____________________________ object is transferred to the _______________________________ object.
Momentum can be transferred in collisions, but the total momentum ________________________________ a collision is the same.
A semi and a car collide… Which will get hit farther?
__________________________________
If they stick together… Which direction will they move?
