1. Momentum & Newton’s Laws

2. Momentum

3. Momentum “Mass in Motion”
Depends on how much stuff is moving and how fast the stuff is moving
Mass x Velocity
Kg * m/s
Magnitude and Direction

4. Comprehension What is the momentum of a…
60 kg halfback moving east at 9 m/s
1000 kg car moving north at 20 m/s
40 kg freshman moving south at 2 m/s
A car posses 20,000 units of momentum. What would the car’s new momentum be if …
Its velocity was doubled
Its velocity was tripled
Its mass was doubled
Both its velocity and mass were doubled

5. Newton’s First Law
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force

6. Newton’s Second Law
An object will only accelerate if there is a net or unbalance force acting upon it
F=ma

7. Newton’s Third Law
For every action, there is an equal and opposite reaction
