Pupil outcome: I can investigate and calculate the size of turning forces. Key learning points: - A moment causes turning. - Moment = force × (perpendicular) distance from the pivot. - Moments are measured in Newton-metres (Nm).

This content introduces the concept of torque as the twisting or turning force that causes rotation, explaining its dependence on the applied force and the perpendicular distance from the axis of rotation. It delves into calculating...
