Fixed point about which object rotates
Turning effect of a force
M=FdM = FdM=Fd (force × perpendicular distance)
Newton-metres (Nm)
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 about a pivot
Sum of anticlockwise moments = sum of clockwise moments
Perpendicular distance from pivot to line of action
