describe the moment of a force 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 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
