moment of a force
... In these diagrams, the magnitude of the moment is the same, but they are in opposite senses. An anticlockwise moment is generally regarded as positive and a clockwise one as negative. In most situations you have two or more forces, each with its own turning effect. You can combine these to give an o ...

... When an elevator you are riding in accelerates downward, you may feel lighter for a short time. If you were standing on a scale during the downward acceleration, the scale would show that you weighed less than usual. Your mass would not have changed, nor would the pull of gravity. What would cause t ...
