Force and Motion
A push or pull which may cause a change in an objects position
Force
Kinetic + Potential energy =
Mechanical Energy
Energy that can be released by a chemical reaction
Chemical Energy
A form of energy that can travel through space and lies partly within the visible range
Light
The soundness of a sound
Volume
The force of attraction between objects, such as the attraction between Earth and objects on it
Gravity
Energy that comes from an electric current
Electrical Energy
The energy that moves between objects of different temperatures
Heat

Moving energy
Kinetic Energy
The flow of electric charges along a path
Electric current
A measure of the number of waves that pass a point in a second
Frequency
not allowing light to pass through
Opaque
A force that acts between two touching objects and that opposes motion
Friction
Stored Energy
Potential Energy
a path along which electric charges can flow
Circuit
Allows all light to pass through
Transparent
Allows only some light to pass through
