Conversion of Energy

The energy can never be created or destroyed, rather converted and transferred.

Any kind of energy that is transferred if it causes an object or thing to move is an example of the conversion of energy.

Below are some of the examples of how various kinds of energy are converted into mechanical energy:

• The gasoline in cars and engines converts chemical energy into mechanical energy.
• The steam in the train converts the thermal energy into mechanical energy.
• In the eardrum, any music that can be heard is converted from sound energy to mechanical energy.
• The human body converts chemical energy to mechanical energy from nutrients into movement.
• When plugged in, the power drill converts the electrical energy into mechanical energy.

On the other hand, mechanical energy can also be converted into various other kinds of energy.

Below are some examples of how mechanical energy is converted into various kinds of energy.

• The windmills convert the mechanical energy into electrical energy for electricity.
• Hitting the drums converts the mechanical energy into sound energy.
• Rubbing the hands together converts mechanical energy into thermal energy.

• Turning a switch on converts the mechanical energy into electrical energy and later on to radiant energy.
• The human body digesting food converts mechanical energy into chemical energy.
