Term | Definition |
---|---|
Conduction | The process by which heat or electrically is directly transmitted though a substance when there is a difference of temperature or of electrical regions, with movement of the matera. |
Convection | The movement cause within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat. |
Radiation | The emission of energy as electromagnetic waves or as moving subatomic particles, especially high energy particles that cause ionization |
Friction | The resistance that one surface or object encounters when moving over another. |
Kinetic Energy | Energy that an object has due to its motion. |
Alt. Energy Source | As solar, wind, or nuclear energy, that can replace or supplement traditional fossil-fuel sources, as coal, oil, and natural gas |
Gravity | The force that attracts a body toward the center of the earth, or toward any other physical body having mass. |
Balanced Forces | If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balaned. |
Chemical Energy | A form of potential energy that is stored in chemical bonds between atoms |
Nuclear Energy | The potential energy stored in the nuclear of an atom. |
Energy Transfer | A change from one form of energy to another. |
Average Speed | Since average speed is the rate position changes average speed =distance traveled/time taken |
Fossil Fuels | A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms |
Thermal Energy | The total kinetic and potential energy of all the particles of an object. |
