Moment of a force/torque
A force whose line of action does not pass through the centre of gravity will cause the body to rotate and translate if it is unopposed – this turning effect is the moment of force.
Human movement is the consequence of an imbalance between the components of these forces that produce rotation the capability of a force to produce this rotation is referred to as torque or moment of force.
The moment of force is the perpendicular distance from the force’s line of action to a specific point or axis of rotation.
Moment = force x distance
