... A shoe pushes on a wooden floor but does not slip. On a microscopic scale, both surfaces are “rough” and high features on the two surfaces form molecular bonds. These bonds can produce a force tangent to the surface, called the static friction force. Static friction is a result of many molec ...

... When a ball is at rest the only force applied on it is static friction. This is the friction (force that resists relative motion) that exists between a stationary object and the surface on which it is resting. When this occurs, there is no pushing or pulling force, the forces are balanced, thus no a ...

... A very important property of a force is that it always involves two interacting objects. You can exert a force by pushing on something, but it wouldn’t mean anything to say that you are exerting a force by pushing on nothing. Similarly, something can push on you, but it’s meaningless to say that you ...
