1. Momentum

2. Quick Video

3. Momentum Momentum can be defined as “inertia in motion."
It is moving mass
All objects have mass; so if an object is moving, then it has momentum
Momentum depends on two things:
mass and velocity

4. Momentum Momentum = mass X velocity p = mv
where p = momentum, m = mass and v=velocity
Unit for Momentum: Kgm/s

5. Which has more momentum and why?
A 1400 kg truck traveling at 50 m/s
Or a 500 kg car traveling at 50 m/s

6. Which has more momentum and why?
A 1400 kg truck traveling at 10 m/s
Or a 500 kg car traveling at 50 m/s

7. Which has more momentum and why?
A 1400 kg truck traveling at 0 m/s
Or a 500 kg car traveling at 0 m/s

8. White board practice
1.  Calculate the momentum of a 0.15 kg ball that is moving toward home plate at a velocity of 40m/s.

9. White board practice
3.  A track athlete throws a 2kg discus into a field with a velocity of 21m/s.  What is the momentum of the discus?

10. White board practice
4.  Calculate the momentum of a 700g ball that is going 0 m/s.
