“ENERGY IS THE

CAPACITY TO DO WORK”

TYPES OF ENERGY

Potential energy is

the energy possessed

by an object by virtue of

its position

Kinetic Energy

Kinetic energy is the energy possessed by an object by

virtue of its motion

The total mechanical

energy of an object is the

sum of its potential

energy and kinetic energy

FORMS OF ENERGY

Electrical energySolar energyMagnetic energyChemical energySound energy

ELECTRICAL ENERGY

Electrical energy is the energy carried by moving electrons in an electric conductor. It

cannot be seen , but it is one of our most useful forms of energy because it is relatively

easy to transmit and use.

SOLAR ENERGY

Solar energy comes from the sun. The word solar means “comes from the sun”. People use

solar cells that change light energy from the sun into electricity.

Solar calculators .Solar panels to heat swimming pools.

Solar panels that provide light and power appliances in homes or other buildings.

MAGNETIC ENERGY

MAGNETIC ENERGY IS THE REGION IN SPACE IN WHICH MAGNETIC FORCE IS EXPERIENCED. IN MAGNETIC ENERGY

LIKE POLES REPEL AND UNLIKE POLES ATTRACT EACH OTHER.

CHEMICAL ENERGY

“Energy stored fuel.”It can be release by a chemical reaction , such as burning or digestion . It is needed to change its

potential into kinetic energy.

Our muscles get energy from the food we eat. The potential energy stored in food is chemical energy .

When it’s released, it gives us kinetic energy to move.

SOUND ENERGY

Sound is energy in the form of vibrations that travel through matter. When a vibration reaches a particle of matter, that particle starts to vibrate , too. In this way, sound vibrations can spread out, not just in a

straight line , but in all directions.

LAW OF CONSERVATION OF ENERGY

“Energy can only be converted from one form to another. It can neither be

created nor be destroyed.”
