Students should be able to:
- describe the moment of a force about a pivot in terms of its turning effect and relate this to everyday examples
- recall and apply the relationship moment of a force (or torque) = force × perpendicular distance from the pivot to new situations or to solve related problems
- state the principle of moments for a body in equilibrium
- apply the principle of moments to new situations or to solve related problems
- show an understanding that the weight of a body may be taken as acting at a single point known as its centre of gravity
- describe qualitatively the effect of the position of the centre of gravity on the stability of objects.
