Produced by the sun and very important for the biosphere
Light energy
The result of movement of tiny particles within an object. The faster they move, the more heat is generated.
Thermal energy
Stored energy which is released when a chemical reaction takes place.
Chemical energy
Used to power machines because it can be transformed into many different forms.
Electrical energy
Stored in objects. When this energy is released, it can do work.
Potential energy
Produced by movement. The heavier an object is and the faster it moves, the more ____ energy it has. Water is an example.
Kinetic energy
Kinetic + Potential energy =
Mechanical energy
When the force of the water moves turbines we call this ______ energy.
Mechanical energy
Describe light energy
Light energy is produced by the sun and very important for the biosphere. There are other natural and artificial sources but the sun is the most important.
Describe thermal energy
Thermal energy is the result of movement of tiny particles within an object. The faster they move, the more heat is generated.
Describe chemical energy and how food gives us energy
Stored energy which is released when a chemical reaction takes place. The chemicals in food are broken down to produce a different form of energy.
Energy made by vibrations in the air.
Sound Energy
Describe sound energy/ sound waves
When an object vibrates, air particles around it vibrate too. This causes sound waves, which we can hear.
Describe Potential energy
Stored in objects. When this energy is released, it can do work.
What is electric energy used for?
To power machines because it can transform into many forms.
What type of energy is this?
Light energy
