The biathlon provides the context for investigating the law of conservation of momentum. Identifies different types of collisions in which momentum is conserved — explosion, hit and stick, and hit and rebound.

Explores the conservation of momentum in two dimensions on location at a curling rink and in the laboratory with an air table. Applies conservation of momentum in two dimensions to the analysis of an automobile accident.

Explores the concept of conservation of momentum in two dimensions in the context of fireworks, bumper cars, open-pit mining, and within the isolated system of an air table. The problem-solving strategy using components is reinforced.

Provides additional information, experiments and problems on concepts presented in the video programs.

Elastic and inelastic collisions are analysed. A montage of sports images reveals that most collisions are inelastic. Uses criteria of conservation of kinetic energy for elastic collisions to solve for an unknown quantity in several examples.

Provides additional information, experiments and problems on concepts presented in the video programs.

Exploring the physics of a soccer game, a projectile spring and a ballistic pendulum, leads to the understanding of the concepts of energy and momentum. Problem solving and combining many physics ideas into one solution is emphasized.

Provides additional information, experiments and problems on concepts presented in the video programs.

Explores benefits and risks in personal safety equipment, and develops a generic Risk-Benefit Assessment model. The model is used to reach personal decisions regarding the use of bicycle helmets.
