Physics - Energy
Question | Answer |
---|---|
Kinetic energy | energy of motion |
Potential energy | energy that is stored as a result of position or shape |
Thermal energy | increases when an object becomes warmer |
Law of Conservation of Energy | energy can be converted from one form to another and cannot be created or destroyed |
Mechanical energy | kinetic energy + potential energy |
Nonrenewable energy | a source of energy that exists in limited quanitities and once used, cannot be replaced except over the course of millions of years |
Heat | the transfer of energy from one object to another because of a difference in temperature |
Temperature | related to the average kinetic energy of the particles in an object |
Potential energy increases | as the temperature of an object rises |
Q=m x c x change in T | specific heat = mass x specific heat x change in temperature |
Radiation | manner by which energy from the Sun reaches Earth |
To transfer thermal energy by conduction and convection, you need: | matter |
Metal | good heat conductor |
