By the time we finish this unit and all related activities you should be able to:

• Define momentum; distinguish between momentum and velocity.

• Distinguish between elastic and inelastic collisions.

• Use conservation principles to solve problems involving elastic and inelatic collisions for initial velocity, final velocity or mass, given the other values.

• Define impulse; distinguish between impulse and force.

• Determine the impulse acting on an object
  • given a F vs t graph
  • given the change in momentum.
• Determine the force acting on an object, given its change in momentum.

Core Content:

Laws of motion. Objects change their motion only when a net force is applied. Laws of motion are used to predict and/or calculate the effects of forces on the motion of objects.
