What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as electrical energy to thermal energy.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

Can energy be created?

Back

No, energy cannot be created; it can only be transformed from one form to another.

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.
