Forces and Motion

Every mechanical wave has its origin in an oscillating object. The particles in the medium themselves oscillate, in a similar...

You saw a situation where the hand was pulled down by a single force, the tension in the shopping bag. It is quite possible...

Physics Narrative 5-11 11-14

Early introductions to forces in equilibrium will be via static situations. However, rather than identifying forces which sum...

This is an account of the origins of the buoyancy force.

Physics Narrative 11-14

The central idea of this episode is laid out in Newton's first law of motion and can be summarised as follows:

Physics Narrative 11-14

In this episode, students will learn about the conditions for static equilibrium (excluding moments of forces).

Lesson 16-19

Many students will recall the principle of moments from earlier work. The application of moments to situations beyond the...
