Energy. energy - the ability to do work or cause change. (Remember- work can only occur if something moves!). Types of Energy. 1) kinetic - energy of an object in motion. 2) potential - the energy of an object’s position or shape. Kinetic Energy. kinetic energy = ½ mass x velocity 2.

Energy energy- the ability to do work or cause change. (Remember- work can only occur if something moves!)
Types of Energy 1) kinetic- energy of an object in motion 2) potential- the energy of an object’s position or shape.
Kinetic Energy kinetic energy = ½ mass x velocity2 Ek= ½ mv2 measured in units of N-m (J)
Gravitational Potenital = Energy weight x height Potential Energy Ep = w x h measured in units of N-m (J)
Forms of Energy 1) mechanical energy- the energy of the position or motion of an object.
2) thermal energy- the total potential and kinetic energy of particles in an object.
4) chemical energy- the potenial energy stored in the chemical bonds.
5) nuclear energy- the potenial energy stored in the nucleus of an atom.
6) electromagnetic energy- the energy of light and other forms of radiation.

convection- the transfer of heat through the movement of a fluid.
conduction- the transfer of heat from one particle of matter to another.
radiation- the transfer of heat through electromagnetic waves.
Law of Conservation of Energy states that energy cannot be created nor destroyed.
