Question | Answer |
---|---|
Chemical Energy | is energy stored in the bonds of atoms and molecules |
Potential energy | stored energy and the energy of position |
Kinetic energy | is motion — of waves, electrons, atoms, molecules, substances, and objects. |
Radiant Energy | is electromagnetic energy that travels in transverse waves |
Thermal Energy | heat, is the vibration and movement of the atoms and molecules within substances |
Mechanical Energy | is energy stored in objects by tension |
Motion Energy | is energy stored in the movement of objects |
Gravitational Energy | energy stored in an object's height. The higher and heavier the object, the more energy is stored |
Electrical Energy | is delivered by tiny charged particles called electrons, typically moving through a wire |
Sound Energy | the movement of energy through substances in longitudinal (compression/rarefaction) waves. |
Energy | The ability to do work |
Conduction | when two objects are at the same temperature |
Radiation | Heat transfer through electromagnetic waves |
Thermodynamics | The study of how heat moves |
Specific Heat | amount of heat per unit mass required to raise the temperature by one degree Celsius |
Insulator | a material that will NOT easily conduct an electric current |
Conductor | a material which electricity, heat or sound can flow through. |
Thermal expansion | the tendency of matter to change in volume in response to a change in temperature |
Temperature | the average kinetic energy |
