WebA mechanical force (external) is necessary to be applied to the ends of the spring if it has to be stretched. The spring is said to possess some energy that remains non-dissipative in it. The spring conserves the energy by regaining its initial shape when the mechanical force acting on it is removed. WebJul 26, 1999 · Mechanics may be divided into three branches: statics, which deals with forces acting on and in a body at rest; kinematics, which describes the possible motions of a body or system of bodies; and kinetics, which attempts to explain or predict the motion … The equations of mechanics are typically written in terms of Cartesian coordinates. … Rotation about a moving axis.
