Types of Energy

What is electrical energy?

• Energy caused by moving electric charges that powers our homes and devices.

• Energy stored in batteries only.

• Energy generated by solar panels exclusively.

• Energy that is only used in industrial applications.

What is light energy?

• Light energy is the energy that is visible to the human eye. It is produced by the movement of photons.

• Light energy is a form of energy that cannot be seen by the human eye.

• Light energy is the energy stored in chemical bonds.

• Light energy is the energy produced by sound waves.

What is sound energy?

• Sound energy is the energy produced by vibrating sound waves.

• Sound energy is the energy produced by moving objects.

• Sound energy is the energy stored in food.

• Sound energy is the energy generated by electrical currents.

What is the relationship between energy and work?

• Energy is the ability to do work.

• Energy and work are unrelated concepts.

• Work is a form of energy.

• Energy is the opposite of work.

What is thermal energy?

• The energy that comes from the temperature of matter and the movement of particles in an object.

• The energy stored in chemical bonds of molecules.

• The energy produced by electrical currents in a conductor.

• The energy associated with the gravitational pull of an object.

What is an example of electrical energy?
