Moment=Force x Perpendicular Distance from Pivot It's written in Newton Metres (Nm) 1 of 5 What is the Principle of Moments? For an object in equilibrium: The sum of the anticlockwise moments about any point = the sum of the clockwise moments about that point. 2 of 5 What is centre of mass? Every object behaves as if its mass were concentrated at one point. This point is called its centre of mass. 3 of 5 What affects stability? The stability of an object is increased by making its base as wide as possible and its centre of mass as low as possible. 4 of 5 Vectors and Scalars A vector is a physical quantity that has a direction A scalar is a physical quantity that does not have direction. 5 of 5
