WebEquilibrium and Statics. When all the forces that act upon an object are balanced, then the object is said to be in a state of equilibrium. The forces are considered to be balanced if the rightward forces are balanced by the leftward forces and the upward forces are balanced by the downward forces. This however does not necessarily mean that ... WebIn physics, a moment on an object is the turning effect on that object caused by a force. If there is a nonzero net moment on an object, the object will rotate around a pivot point. On the other hand, if an object is balanced (i.e. not spinning or spinning at a constant rate), then this means that the net moment on the object is zero.
