1. Action and Reaction

2. Ex: A rhino has large momentum because of its high velocity.
Momentum- a property a moving object has because of its mass and velocity.
Ex: A rhino has large momentum because of its high velocity.
Ex: Elephant has large momentum because of its large mass.

3. Law of conservation of momentum- the total amount of momentum does not change unless outside forces act on the object.

4. Moving
s = 20 m/s
Stop
s = 0 m/s

5. Slow down
s = 10 m/s
Moving
s =10 m/s

6. Momentum Equation Variable Ending Units P = Momentum kg m/s
m = mass kg
v = velocity m/s .

7. Momentum Equation
P = m X v
m = P / v
v = P / m P . . X v m
