Energy and Its Sources

Energy is an important element in daily life since it used for many activities like moving vehicles, promoting growth of the human body, and enabling humans to think. However, energy can be found in various forms like sound, heat, motion, and light though they are classified into kinetic and potential energy. While kinetic energy is the motion of substances, waves, objects, molecules, and atoms; potential energy is gravitational or stored energy. Some major examples of kinetic energy include thermal, radiant, electrical, motion, and sound while potential energy includes nuclear and chemical energy.

Converting Energy from One Form to Another:
