# AS Physics Statics

Define Vectors
A quantity which has direction as well as magnitude
1 of 10
Define Centre of Mass
The point through which a single force on a body does not cause the body to turn
2 of 10
Define a Moment
Force x Perpendicular distance from the pivot to the line of action of the force
3 of 10
What is the Moment Equation?
Moment = Force x distanace
4 of 10
Define Principle of Moments
For an object that is in equilibrium, the total clockwise moment about a point is equal to the total anticlockwise moment about the same point
5 of 10
Define Equilibrium
A system is in equilibrium if there is no resultan force and no resultant moment
6 of 10
Define Moment of a Couple
One force x perpendicular distnace between the lines of action of the two forces
7 of 10
