Question | Answer |
Energy | the ability to do work . can never be created or destroyed. gives the ability to do work; a scalar physical quantity that describes the amount of work that can be performed by a force, an attribute of objects and systems |
mechanical energy | energy that can be used directly to do work. the sum of potential energy and kinetic energy present in the components of a mechanical system |
Potential Energy | Stored energy. Energy that is capable of doing useful work if it was released. . potential energy is the energy which is possessed by the virtue of its position |
kinetic Energy | moving energy. the energy possessed by a body by the virtue of its motion or movement |
Chemical Energy | the energy set free in a chemical reaction. It is a form of potential energy and results from the making and breaking of chemical bonds. |
Electrical Energy | energy of moving electric particles; form of potential energy |
Heat Energy | total kinetic energy of all the particles of a substance |
Light Energy | energy given out by light sources; only form of energy that you can see directly |
Sound Energy | energy present in a sound wave, vibrations of the air molecules |
Renewable Energy | source of the energy is still there after the energy is taken from it. e.g.: wind, solar, hydroelectric |
Non-Renewable Energy | source of the energy is gone after the energy is taken from it. e.g: nuclear energy, fossil fuels |
The Sun, our star | Most energy originally comes from this |
Work | Energy allows this to be done. i.e.: a forces through a distance |
Electricity | convenient energy used at home |
Watt | Unit of Power |
Reservoir | Lots of water can be stored in this |
Insulation | Reduces heat loss in a house |
Nuclear Energy | Energy released by splitting atoms nucleus |
Chemical Energy | type of energy stored in batteries |
Potential energy | Energy with capacity to do work |
Coal | a type of dark fossil fuel we burn |
Motor | electrical energy changes to mechanical energy |
Bulb | electrical energy changes to light and heat energy |
Battery | chemical energy changes to electrical energy |
Microphone | Sound energy changes to electrical energy |
