Momentum

Momentum. Impulse Momentum Conservation of Momentum. Reading Question. Impulse is. 1. a force that is applied at a random time. 2. a force that is applied very suddenly. 3. the area under the force curve in a force-versus-time graph. 4. the time interval that a force lasts.

  4. Reading Question The total momentum of a system is conserved 1. always. 2. if the system is isolated. 3. if the forces are conservative. 4. never; it’s just an approximation.

  10. Student Workbook

  11. Student Workbook Why? when the force is constant

  12. Student Workbook Do both carts receive the same inpulse? Yes, they both have the same force applied for the same amount of time. Do both carts start with the same momentum? Yes, they both have the same mass and velocity. So they both have the same final momentum. Do they both have the same final velocity?

  13. Class Question The cart’s change of momentum is 1. –30 kg m/s. 2. –20 kg m/s. 3. –10 kg m/s. 4. 10 kg m/s. 5. 30 kg m/s.
