Document Summary
Energy is a scalar property of an object or collection of objects (j joules = kg. m2/s2) There are many types of energy, which can be converted from one type to another or one part to another o o o o o o. Translational kinetic energy: energy of translational motion (motion in straight line) Gravitational energy: energy due to gravitational interactions between objects. Elastic energy: energy stored in a material when it is deformed (e. g. springs) Internal: energy of motion of atoms and molecules in gases liquids and solids. Kinetic energy energy due to motion (less than speed of light) => k = (1/2) m v2 => kg, m/s. Potential energy energy due to interaction with a field (gravitational) attract or repulse. Rest energy intrinsic energy of a particle. The total energy of the universe is a constant this is known as the principle of energy.
