Question

Write a short note on different forms of energy?

Answer 1

There are many forms of energy: like solar, wind, wave and thermal to name a few, but the 6 Forms of Energy we study in Needham are: Sound, Chemical, Radiant, Electric, Atomic and Mechanical. Sound Energy- is produced when an object is made to vibrate. Sound energy travels out as waves in all directions.

Best of luck!

Answer 2

Answer:

1. Heat or thermal energy
2. Chemical energy
3. Sound energy
4. Electrical energy
5. Potential energy
6. Kinetic energy
7. Solar energy
8. Mechanical energy

Explanation:

1. Heat or thermal energy

The energy possessed by a body due to its temperature is know as heat or thermal energy.

2. Chemical energy

The energy released in chemical reactions is known as chemical energy.

3. Sound energy

The energy of vibrating body producing sound is known as sound energy.

4. Electrical energy

The energy of moving electrons in a conductor connected with a battery is known as electrical energy.

5. Potential energy

The energy possessed by virtue of its position is called potential energy. P.E= mgh

6. Kinetic energy

The energy possessed by a body by virtue of its motion is called kinetic energy.

K.E= 1/2 mv²

7. Solar energy

The energy radiated by the sun is known as solar energy.

8. Mechanical energy

The energy possessed by a body because of its speed or position or change in shape is called the mechanical energy. It is the sum of kinetic energy and potential energy of a body.

M.E= P.E + K.E

Hope this is helpful
