Document Summary
Energy : the ability to do work, can change on form and be turned into heat. Work : the magnitude of a force multiplied by the distance that the force moves in the direction of the force. The transfer of energy from one object to another. Heat : something that raises the temperature of a material, as measured by the thermometer. Done by making atoms move (in a gas) or vibrate (in liquids or solids) faster. Fuel cells : converts chemical energy directly to electricity. Kinetic energy : energy of motion (energy stored in a moving bullet or an asteroid) Potential energy: stored energy (i. e energy stored in a compressed string) Nuclear energy: energy stored in the forces between pairs of the atomic nucleus, Mgh (mass x gravity(9. 8 m/s^2 ) x height ) released when the nucleus is broken. Gravitational energy: energy that an object has at high altitude, when it falls, energy converted to kinetic energy.
