Chapter 9. Momentum

Supporting pages (HTML pages with embedded animations)

Momentum, Newton's laws and collisions
Background to: Newton’s laws of motion in terms of momentum. What is an external force? Collisions (including motor vehicles). Components and conservation. Elastic and inelastic collisions. The centre of mass frame. Approximations.

Collision examples and calculations
Analysis of the hammer-brick-chest collision and of the ballistic pendulum. Some important problem solving techniques. Identifying similarities in problems. Includes

Collisions in two dimensions
Analysing collisions in two dimensions. Solving for final velocities using momentum conservation in two dimensions, plus two other data, which may include energy conservation for elastic collisions.
A simple introduction to calculus: Differentials and integrals
