Unit 4 pretest-FORMS OF ENERGY & ENERGY TRANSFORMATION

Front

What is energy transformation?

Back

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

Front

What type of energy is associated with the movement of objects?

Back

Mechanical energy is the energy associated with the movement of objects from one place to another.

Front

What are the by-products of nuclear energy?

Back

The by-products of nuclear energy include radioactive waste, which can be harmful to the environment.

Front

What energy transformation occurs in a wind turbine?

Back

In a wind turbine, mechanical energy is transformed into electrical energy.

Front

Where does a pendulum have the most kinetic energy?

Back

A pendulum has the most kinetic energy at its lowest point (position 3).

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons, often used to power devices.

Front

What is mechanical energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves.
