Lesson:

Get out your momentum problems (pass back)

review #’s 1 through 4

conservation of momentum

Momentum Chapter

Stepping In: Paired Reading

  • Pages 21 and 22

  • Copy and Answer in your science notebook:

  1. What is the law of conservation of momentum?

  2. What is the only thing that can interfere with conservation of momentum? Explain.

  3. What are two kinds of collisions that can occur?

Discussion and application:

Elastic and inelastic collisions.

Collision Sim: PhET Collisions Lab

Demonstrate Sim

Assignment:

Simulate, sketch, and analyze the following collisions.

  1. Any elastic collision

  2. Any inelastic collision

  3. A collision with a small mass hitting a large mass.

  4. A large mass hitting a small mass.

For each:

  • Label and sketch the masses before the collision

  • label them with momentum vectors that include the magnitude and units.

  • Label and sketch the masses After the collision

  • label them with momentum vectors that include the magnitude and units.

  • Mathematically compare the momentum before and after the collision and check to see if momentum is conserved.
