Energy
Mechanical energy is the energy possessed by an object due to its motion or its
Term | Definition |
---|---|
energy | Ability to do work |
kinetic energy | Energy in motion |
potential energy | Stored energy and object has which can change based on its position or shape |
thermal energy | Heat energy - fast the particles are moving the hotter the object is |
electrical energy | Energy resulting in the movement of charged particles |
chemical energy | The energy stored in chemical bonds of molecules |
law of conservation of energy | Energy cannot be created or destroyed, only transferred |
energy transformation | Takes place when energy changes from one form into another form. |
sound energy | Energy that creates noise through vibrations |
radiant energy | Energy that is produced by the vibrations of electrically charged particles (sun, light, radio waves) |
nuclear energy | Energy that is in the nucleus of an atom and powers the sun |
fusion | The combining of atoms (occurs in the sun) |
fission | The splitting of atoms (occurs in nuclear reactors) |
fossil fuels | Non-renewable resources such as: coal, natural gas, petroleum |
conduction | The transfer of heat energy through direct contact of particles within the substance |
radiation | The transfer of heat energy through infrared rays |
convection | The transfer of heat energy through the movement of particles in a liquid or a gas |
temperature | A measure of the average kinetic energy of the particles in a sample matter |
heat | Thermal energy that flows from one object to another and is measured in Joules |
absolute zero | The temperature at which all particle motion stops (It is the coldest possible temperature) |
