Types of energy
What is Kinetic Energy?
Energy of movement or motion.
What is the Law of Conservation of Energy?
This states that energy cannot be created nor destroyed but is transformed.
Energy is measured in this
Joules
What is potential energy
The type of Energy that depends on mass and position and is stored.
Explain the transformation that takes place when you rub your hands together.
Kinetic energy from rubbing hands to heat energy from friction.
Its is stored energy
Potential energy
What is electrical energy
Type of energy that depends on the flow of electrons
Explain the transformation of a book falling from table.
The term used for energy changing to another.
Energy Transformation
What energy is stored in bonds of chemicals or food?
Chemical energy.
Explain the transformation of energy that occurs in a coal burning power plant.
Chemical energy to heat energy (burning coal) to kinetic energy (spinning generator) to electrical energy.
Energy is the ability to do what?
Work and cause changes.
What is the type of potential energy that occurs when you press down a spring?
Elastic potential energy.
Energy transformation is not efficient. There is useful energy and what other kind of energy?
Wasted energy. Usually as heat.
The Law of Conservation of Energy says that...?
Energy cannot be created nor destroyed. It is transformed instead.
