Hangabtriebskraft (f)

downhill force (n)

A body on an inclined plane will move down the slope if the downhill force FD is greater than the kinetic friction force FK.

When a force acts on one of the bodies, the body will only begin to move relative to the surface underneath it when the external downhill force is greater than the static friction.
