Forms of Energy

Energy

The ability to do work. it makes things move and change

Light Energy

energy that allows us to see

reflection

The bounce light, sound, or heat off of a surface

Bend (refract)

when light travels from air to another substance it causes the light to change speed

absorb

to take in without reflecting or transmitting energy

sound energy

energy we hear that is produce by the vibration

vibrations

quickly moving back and forth sound is a type of energy made by vibrations

pitch

the relative frequency (high or low) of a sound as perceived by a listener

heat (thermal) energy

energy that keeps us warm

conductor

Materials that heat and/or electricity flows through easily

Insulator

A material used to reduce or prevent the transformation of electricity

Heat transfer

when heat energy moves from a hotter object to a colder object

Chemical energy

potential or stored energy that can be released by a chemical reaction

mechanical energy

energy that an object has due to it’s motion or it’s position

closed circuit

a continuous path through which electricity can flow

open circuit

a circuit in which continuity is broken so electricity cannot flow

Energy Transformation

A conversion or change in energy form

electrical energy

comes from the movement of charged particles can be converted into heat, light sound or mechanical energy
