FORMS OF ENERGY & ENERGY TRANSFORMATION

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, electrical, chemical, and nuclear.

Front

What are the main forms of energy?

Back

The main forms of energy include kinetic energy, potential energy, thermal energy, electrical energy, chemical energy, and nuclear energy.

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 light energy.

What type of energy transformation occurs in a hydroelectric power plant?

Back

In a hydroelectric power plant, mechanical energy from moving water is transformed into electrical energy.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, including light. It is the form of energy produced by a lamp when it is turned on.

Front

What are by-products of nuclear energy?

Back

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

Front

What type of energy transformation occurs in an electric pencil sharpener?

Back

In an electric pencil sharpener, electrical energy is transformed into mechanical energy to sharpen the pencil.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a rock at the top of a hill has gravitational potential energy.
