Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy. In Newtonian physics, there is a universal law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.
What law states, in part, that energy can change from one form to another?
A: Newtonian physics

The city was also home to the Royal Naval Engineering College; opened in 1880 in Keyham, it trained engineering students for five years before they completed the remaining two years of the course at Greenwich. The college closed in 1910, but in 1940 a new college opened at Manadon. This was renamed Dockyard Technical College in 1959 before finally closing in 1994; training was transferred to the University of Southampton.
