3. Momentum p = mv momentum mass velocity

4. Units p = m·v = kg·m/s

5. Scalar or Vector p = m·v velocity is a vector Momentum is also a vector

6. Example Carson (9 kg) is sitting in a pumpkin patch. How much momentum does he have?

7. Example Miles (60 kg) just stole the basketball from his opponent and is running down the court at a rate of 5.5 m/s. What is Miles’s momentum?

8. Collisions Elastic End up apart from one another Inelastic Stick together Simulation

9. The total momentum of any group of objects remains the same unless acted on by outside forces.

11. Total Momentum Before Total Momentum After =

12. Example

13. Example Abdi shoots a paintball gun which shoots a.05 kg paintball at a speed of 20m/s. If the gun has a mass of 6 kg, what is the speed of the gun as it kicks back into his shoulder? BeforeAfter GunPaintballGunPaintball v = 0 m/s v = ?v = 20 m/s

14. Example cont’d Gun PaintballGunPaintball m = v = p = m = v = p = m = v = p = m = v = p = Total p =
