1. Momentum

2. How is momentum calculated?
Momentum depends on 2 things
Mass
Velocity

3. How is momentum calculated?
Use the triangle method again!
Momentum
Velocity
Mass

4. How is momentum calculated?
Use the triangle method again!
Momentum =
Mass * Velocity
Units = kg * m/s

5. How is momentum calculated?
Use the triangle method again!
Mass =
Momentum/Velocity
Units = kg

6. How is momentum calculated?
Use the triangle method again!
Velocity =
Momentum/Mass
Units = m/s

7. How is momentum calculated?
Use the triangle method again!
Velocity =
Momentum/Mass
Units = m/s

10. Examples
A ball with a mass of 2Kg has a momentum of 25 kg·m/s. What is the ball's speed?
12.5m/s

11. Examples
A ball with a mass of 1.5Kg is thrown at a speed of 10 m/s. What is the ball's momentum?
15kg * m/s

12. Examples
A ball is moving at a speed of 7.0 m/s and has a momentum of 100 kg·m/s. What is the ball's mass?
14.3 kg

13. What is the relationship between momentum, mass, and velocity?
Mass and velocity both affect momentum
To determine how, just look at the math problem
