Question

Give two examples of one form of energy changing into another form.​

Answer 1

Answer:

Energy cannot be stored and it can only be transformed into other forms of energy.

Explanation:

• If we take an example of light , Electrical energy transforms to light energy.
• If we take an example of  muscular energy , it transforms to work energy.

Hope it helps you

Answer 2

Answer :

Two examples of one form of energy changing into another form are as follows :

• Hydroelectric power plant
• Automobiles

Explanation :

• In hydroelectric power plant, huge amount of water is stored in dams which are are built at height. It possesses potential energy as water at such height, when the water is released from the height, the potential energy gets converted into kinetic energy. This kinetic energy of the the moving water is then used to move the blades of the turbine which helps in producing electricity.

• In Automobile the chemical energy of the fuel gets converted to heat energy. Then, this heat energy turn moves the piston and gets converted into mechanical energy. The vehicle moves due to the movement of piston, and converting the mechanical energy to kinetic energy.

Some more examples are :

» In loud speakers, electrical energy gets converted to sound energy.

» In a solar cell, light energy gets converted to electrical energy.

» In a dry cell, chemical energy gets converted to electrical energy.

» In, Rollar coaster Potential energy gets converted to Kinetic energy.
