Mechanics (Mechanik)


A force is a physical quantity which causes a change in the motion of a body or in its form. A force has both magnitude and direction, and is therefore classified as a vector quantity. When specifying a force, it is not enough to specify the magnitude and direction of the force. It is also necessary to specify where a force acts, and this is done by specifying its line of action. An external force may be applied at any point along its line of action without changing its effect on the body
