Energy Vocabulary • Energy – the ability to do work or cause change • Kinetic energy – the energy an object has because of its motion • Potential energy – stored energy due to the position or shape of an object • Gravitational potential energy – potential energy due to an object’s height • GPE = weight x height • Elastic potential energy – the potential energy associated with objects that can be stretched or compressed • Mechanical energy - the form of energy associated with the position and motion of an object. • ME = PE + KE • Thermal energy – the total potential energy and kinetic energy of particles in an object • Electrical energy – the energy from electrical charges • Chemical energy – potential energy stored in chemical bonds that hold compounds together • Nuclear energy – the potential energy stored in the nucleus of an atom • Electromagnetic energy – energy that travels in waves (like sunlight) with some electrical and some magnetic properties
