What is energy transformation?

Back

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

Front

What is an electrical conductor?

Back

An electrical conductor is a material that allows electric current to flow through it easily.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to flow through it easily.

Front

What type of energy does a thermometer measure?

Back

A thermometer measures the average kinetic energy of particles in a substance.

Front

What does an electric clock need to keep time?

Back

An electric clock needs energy from an electrical outlet to keep time.

Front

Give an example of energy transformation in daily life.

Back

Taking an elevator to the top of a tall building is an example of transforming electrical energy into motion energy.

Front

What happens to energy in a closed system?

Back

In a closed system, energy is conserved; it can change forms but cannot be created or destroyed.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which depends on the mass and speed of an object.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state.

Front

How do conductors and insulators differ in terms of electron movement?

Back

A conductor has electrons that are free to move, while an insulator does not.
