When we push or pull a door, we are applying a force that causes a turning effet to accomplish a task. This turning effect is called the moment of a force, and is used to make work easier.
We can either call the fulcrum a fulcrum, or a pivot, which is the point of rotation, is defined by the following equation:
Moment of a force, M = F x d
Moment of a force, M = Force x Perpendicular distance from the fulcrum to the line of action of the force.
Since the S.I. unites of force and distance are both newton(N) and metre(m), the moment of force has derived unit of newton-metre(N m).
