... Weight–a measure of the gravitational force acting on an object – Weight depends on an object’s location – The weight of an object would be very different on the earth and on the moon, and still different in outer space – On the moon, the object would have only one-sixth the weight it has on the ear ...

Friction Force - NeuLog Sensors
... Friction force is created when two surfaces move or try to move against each other. The direction of the friction force is always opposite to the direction of motion (or motion attempt) and parallel to the surface, therefore it resists the relative motion of the surfaces. Friction force depends on t ...
