Ball Sports L2-Oblique Collisions

OUTCOME

By the end of this lesson you will be able to apply trigonometry and the law of conservation of momentum to collisions on a pane (flat surface) to examine collisions between rolling balls

Engage

The law of conservation of momentum is explained qualitatively and mathematically through examples involving billiards and roller skaters.

LEARNING TASKS

Explain

1. Describe the information your need to know before a collision to solve a billiard ball problem

2. How are vectors used in the analysis of the velocities?

Explore and Elaborate

Activity: Oblique Ball collisions

1. Film a collision between two balls using tracker,

2. Use conservation of momentum analysis to estimate if this is an elastic collision

Evaluate
