Learning Outcomes for Momentum and Collisions

 

Lesson Plans || Learning Outcomes and Activities || Teacher Notes || Labs

 

The list below displays sample learning objectives for the unit on Momentum and Collisions. The various activities from the Lesson Plans have been organized by objective. This format of organizing The Physics Classroom's activities may be more useful to some teachers than the Lesson Plan format. It is worth noting that the activities identified below only include those activities included on the Lesson Plans and in the Pre-Built Task Tracker courses. Additional activities are referenced on the Teacher Notes page.

 

1. Momentum

Define momentum and identify its units; relate the quantity of momentum to the variables that affect it and identify the direction of the momentum vector.

2. Impulse-Momentum Change Relationship

Describe what an impulse is and relate it to the amount of momentum change that it causes; use the impulse-momentum change relationship to analyze physical scenarios and to predict the effect that a variable change would have upon the outcome.

3. Action-Reaction and Momentum Conservation

Use Newton's third law and second law to compare the force, the collision time, the impulse, the momentum change, and the velocity change of the two objects involved in a collision or explosion; explain and use the law of momentum conservation.

4. Momentum Conservation and Explosions

Analyze an explosion situation involving two objects to show that momentum is conserved and conduct an analysis to predict the post-explosion speed of one of the objects.

5. Momentum Conservation and Collisions

Conduct a momentum analysis of a collision to show that system momentum is conserved and to use such a momentum analysis to predict an unknown post-collision velocity.

6. Momentum Conservation and Proportional Reasoning

Use proportional reasoning skills to predict the post-collision velocity of an hit-and-stick collision when the mas ratios of the colliding object and the initial speed are known (one object initially at rest).
