Energy Examples
A roller coaster sitting at the top of a track waiting to move has what type of energy?
Potential
This type of material lets light pass through so you can see clearly through it.
Transparent
What does sound energy need in order to travel?
A medium (solid, liquid or gas)
This type of heat transfer allows you to feel the warmth from a bonfire without touching it.
Radiation
The Law of Conservation states that energy _________.
Cannot be created or destroyed.
An apple falling from a tree has what type of energy?
Kinetic
This type of material lets SOME light through, but you cannot see clearly through it.
Translucent
Sound cannot travel through this because there are no particles to vibrate.
Space or Vacuum
This type of heat transfer occurs through direct contact between objects.
Conduction
When a drum is hit, energy moves from your hand to the drum and then through the air as this energy.
Sound energy
A fan, TV and lamp plug into an outlet and use what type of energy to work?
Electrical
This happens when light bounces off a surface, like a mirror.
Reflection
Sound energy begins with a rapid back and forth motion of objects called what?
This type of heat transfer happens when warm air or liquid moves in currents.
Convection
A toaster changes electrical energy into this type of energy to brown your bread.
Thermal energy
Mechanical
This type of object does NOT let any light pass through it.
Opaque
Sound travels the fastest through which type of material?
Solids, Liquids, or Gases
Solids
Toching hot sand with your feet is an example of what type of energy transfer?
Conduction
Turning on a TV transfers electric energy into sound energy and ______ energy.
Light
Batteries, fuel and food are all examples of what type of energy?
Chemical
This occurs when light bends as it passes through water or glass, creating rainbows.
Refraction
Sound energy does not travel in a straight line, but instead travels in ______.
Water boiling in a pot is an example of what?
Convection
When a roller coaster moves quickly over tracks, some of the energy is transfered to thermal energy because of what force?
Friction
