it travels slower through matter. Examples can be glass, water and air
what is electrical energy?
Electrical energy is the movement of electrons through a conductor.
What is the most common form of energy?
Electrical energy
How is kinetic energy created?
Potential energy converts into kinetic energy when it begins to move
What does sound need inorder to move? Give examples
Sound needs matter. Examples can be air and water
What is the difference between chemical and electrical energy?
Chemical energy is potential (stored) energy which is then converted to kinetic energy to be used. in essence its energy released through a chemical reaction for example eating food. Electrical energy is the movement of electrons from one atom to another.
What is the law of conservation of energy?
Energy can neither be created nor destroyed.
* only converted from one form to another
