a material that readily allows electric charges to pass through it and therefore carries electricity well.
a path along which electric charges can flow.
the ability to cause changes in matter.
a material that resists the flow of electric charge and therefore does not conduct electricity well.
energy an object has because of motion.
materials that don’t let any light pass through them.
energy that an object has because of its position or its condition.
it happens when light bounces off an object.
the bending of light.
a material through which an electric change cannot move easily.
the build up of electric charges on an object.
to change from one form into another.
materials that let some light pass through them.
materials that let nearly all light pass through them
the back-and-forth motion of an object.
to take up and store energy without reflecting or transmitting that energy.
to transmit heat or electricity through a medium.
the relative frequency (high or low) of a sound as perceived by a listener.
to bounce light, heat, or sound off of a surface.
the flow of electric charges along a path.
the process of transferring heat from light waves through space.
radiation that we can see.
the energy moving particles have.
the transfer of heat between objects that are touching.
the transfer of heat by a moving liquid or gas.
energy that is stored in matter that can be released by a chemical reaction.
the total energy of motion and the position of an object.
a device that changes electrical energy into mechanical energy.
