this is a ppt on energy

1. How the world
works
Everything in the
world works from
energy.

2. What is energy?
 Energy is all what is required to
do anything. In simple
words, energy is the ability to do
any kind of work.
 All the energy in our body comes
from food we eat.
 Energy can be converted from
one form to another.

3. Types of energy
 There are various types of
energy like-
 Solar energy
 Light energy
 Magnetic energy
 Chemical energy
 Mechanical energy
 Sound energy and so on.

4. Solar Energy
Solar energy is the energy which is
given out by the sun.
It is very important for us.

5. Light Energy
 We get light energy from lights
all around us.
 Light energy can be also
converted into electric energy
like a tube light or bulb

6. Magnetic Energy
 Magnetic energy takes place
when it pulls metallic things.
 Because of magnetic energy
only, it can pull these things.

7. Chemical energy
 Chemical energy can encompass a
lot of different types of energy
like potential types of energy
and kinetic energies. Chemical
energy is a form of potential
energy.

8. Mechanical Energy
 In physics, mechanical energy is
the sum of potential energy and
kinetic energy present in the
components of a mechanical
system. It is the energy
associated with the motion and
position of an object.

9. Sound energy
 Sound energy is the energy
produced by sound vibrations as
they travel through a specific
medium. Sound vibrations cause
waves of pressure which lead to
some level of compression and
rarefaction in the mediums
through which the sound waves
travel. Sound energy
is, therefore, a form of
mechanical energy.
