Heat & Light
What form of energy lets you see things?
light energy
A rolling ball or a running person has this kind of energy
motion or kinetic
Energy that is waiting or held and not being used is called potential or this kind of energy.
stored energy
A TV changes electrical energy into what two main forms of energy?
light and sound energy
A television takes electrical energy and changes it into light energy and this other form.
What is Sound Energy?
What form of energy makes things feel warm?
heat or thermal energy
What form of energy is produced when something vibrates?
sound energy
A battery stores energy in this form, which is released when you use it.
chemical energy
A campfire changes the chemical energy stored in wood into these two forms of energy
Heat/Thermal Energy and Light Energy
A solar panel changes light energy from the Sun into this useful energy for your house.
What is Electrical Energy?
The Sun is a natural source for both heat energy and this form of energy
light energy
The faster something is moving, the more of this form of energy it has.
motion or kinetic
Food, like a piece of bread, holds this form of stored energy for your body.
chemical energy
A simple toy crank flashlight changes the motion energy from your hand into this useful type of energy.
electric energy
Rubbing your hands together converts motion energy into this form of energy.
What is Heat or Thermal Energy?
Rubbing your hands together quickly makes friction, which converts motion energy into this?
heat energy
This form of energy is carried by waves through the air to your ear.
sound energy
A stretched rubber band or a pulled-back bow and arrow are examples of this kind of potential energy.
elastic potential energy
In a car engine, the chemical energy in gasoline changes to heat energy, which then changes into this energy to make the car move
motion or kinetic energy
When you turn on a light switch, electrical energy changes into light energy and a small amount of this.
.What is Heat or Thermal Energy
A toaster converts electrical energy into light energy and this other form of energy to cook bread.
heat or thermal energy
A wind turbine converts motion energy from the wind into this useful type of energy.
electrical energy
A ball sitting at the top of a tall slide has a lot of this type of stored energy because of its height.
Gravitational Potential Energy
When energy changes from one form to another, it is called an energy this.
transformation
The chemical energy in wood is converted into light and heat when you do this to it.
What is burning or setting it on fire?
