the ability to cause changes in matter
the total energy of motion and position of an object
Energy caused by movement of electric charges
A form of kinetic energy that is carried as waves in vibrating matter
When an object compresses the air around it by moving backwards and forwards, producing sound
A form of energy that can travel through space and lies partly within the visible range
Energy produced by the sun
the total amount of kinetic energy of the particles of a substance (energy produced by heat)
Energy that can be released by a chemical reaction (energy stored in molecules)
flow of electric charges Complete circuit (closed circuit)
Complete circuit (closed circuit)
an electric circuit that is a complete pathway made of conductors through which electric current can flow
Incomplete circuit (open circuit)
an electric circuit that is an incomplete pathway
blocked by insulators, an open switch or a broken path through which electric current cannot flow.
an electric circuit in which electric charges have only one path to follow.
an electric circuit that has more than one path for the electric charges to flow.
the bouncing of light waves when they encounter an object.
the bending of light waves as they pass from one material to another.
a material substance (solid, liquid, gas or plasma) that allows energy waves to travel through.
a transparent object that bends and separates white light into the colors of the rainbow.
not allowing light to pass through.
allows light to pass through.
allows only some light to pass through.
