Energy: Its Form and Transformation

Major Kinds of Energy

​

• Potential Energy
• Kinetic Energy

1. Potential Energy

• Potential Energy is an energy that is stored in a n object at rest.
• Ex: Stretched rubber band

2. Kinetic Energy

• Kinetic Energy is energy in motion.

​

• Ex: A ball rolling on the ground

Kinetic and Potential Energy

Different Forms of Energy

• 1. Mechanical Energy
• 2. Chemical Energy
• 3. Radiant or Light Energy
• 4. Electrical Energy
• 5. Sound Energy
• 6. Thermal or Heat Energy
• 7. Nuclear Energy

​

1. MECHANICAL ENERGY

• Mechanical energy is a form of energy possessed by moving objects.
• It can either be Kinetic or Potential Energy.

MECHANICAL ENERGY

2. CHEMICAL ENERGY

• Chemical Energy is a type of energy stored in molecules.
• Food from plants and animals contain chemical energy.

3. RADIANT OR LIGHT ENERGY

• Radiant or Light Energy is a form of energy that travels in an empty space.
• It can be in form of Light, ultraviolet rays, x-rays and radiation.

Radiant Energy

4. ELECTRICAL ENERGY

• Electrical Energy is produced by moving Electrons.

Electrical Energy

• Static Electricity- is produced when two different materials are rubbed to each other.
• Current Electricity- is flowing electricity

5. SOUND ENERGY

• Sound Energy is the energy produced by vibrating objects. When objects vibrate, sound is produced.

6. THERMAL OR HEAT ENERGY

• Thermal Energy is present in everybody because of the motion of molecules.

7. NUCLEAR ENERGY

• Nuclear Energy is produced during Nuclear Fusion and Nuclear Fission.
