Moments, Levers & Gears (AQA GCSE Physics): Flashcards

Fixed point about which an object can rotate

Turning effect of a force

$M = Fd$

Newton-metres (Nm)

Perpendicular distance from pivot to line of action of force

Increase force or increase perpendicular distance

Decrease force or decrease perpendicular distance

Greater rotational effect

Less rotation

Clockwise and anticlockwise

Total clockwise moment = total anticlockwise moment

Sum of anticlockwise moments = sum of clockwise moments

No rotation, object remains stationary
