moment of a force
/ ˈmoʊmənt əv ə ˈfɔːrs /
In physics, measure of the turning effect, or torque, produced by a force acting on a body. It is equal to the product of the force and the perpendicular distance from its line of action to the point, or pivot, about which the body will turn. Its unit is the newton meter.
If the magnitude of the force is F newtons and the perpendicular distance is d meters then the moment is given by:
moment = Fd
