... If we release the mass after pulling it aside, the spring will accelerate the mass, and it will return to the equilibrium position, but at that moment, where the potential energy is zero, the potential energy will have been transformed into kinetic energy (energy of motion) which is given by (1/2)mv ...

... Another typical example is the bicycle (Fig. 1b). We can move more quickly on a bicycle than on foot. There are also other types of machines, which do not save energy or increase velocity, but are used to change directions of the applied forces conveniently. A fixed pulley is one of the typical exam ...

In contrast, energy is only conserved when certain types of forces are exerted between the objects. Collisions are classified as elastic (kinetic energy is con ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
