4. Physics
Physics is the science of matter and its motion,
space-time and energy. Physics describes
many forms of energy - such as kinetic energy,
electrical energy, and mass and the way energy
can change from one form to another.
Everything surrounding to us is made of matter.
5. Importance of Physics
The main and the important form of energy that is
electrical energy is only and only due to the
physics. We cannot image the life without electricity.
When we switch on the button the Fan starts and
when we switch off the Fan Stops, all are the
Physics.
6. Electricity
THE ELECTRICITY IN OUR HOUSE IS A GIFT OF PHYSICS.
HYDROELECTRIC PROJECT IS THE METHOD IN WHICH
WATER IS USED TO GENERATE ELECTRICITY. THE
MECHANICAL ENERGY OF THE WATER IS CONVERTED
INTO ELECTRICAL ENERGY USING DYNAMO.
7. Physics is also applied in our body.
Due to electrical signals, which
carry the sensation, to mind, we
are able to see, listen or to feel the
objects.
8. Newton's Law of Motion
WE WALK, WALK FAST, RUN, JOG, JUMP ETC. ALL
THESE OR ANY TYPE OF MOTION IS ASSOCIATED
WITH NEWTON'S LAW OF MOTION.
9. 1St Law Of Motion
An object at rest stays at rest, unless an
external, unbalance force acts on it.
10. Newton's 2nd Law Of Motion
If we use the same force to push a truck and push a
car, the car will have more acceleration than the
truck, because the car has less mass.
It is easier to push an empty shopping cart than a
full one, because the full shopping cart has more
mass than the empty one.
11. Newton's 3rd Law Of Motion
When you jump off a small rowing boat into
water, you will push yourself forward
towards the water. The same force you
used to push forward will make the boat
move backwards.
12. Gifts Of Physics

13. Physics in Our Daily Life
• WHEN WE TALK, OUR VOCAL CORDS VIBRATE
PRODUCING SOUND.
• WHEN WE EAT FOOD, THE CHEMICAL ENERGY OF
THE FOOD IS BEING CONVERTED INTO
MECHANICAL ENERGY WHICH WE USE TO DO
DIFFERENT TYPES OF WORK.
14. Physics in Telephone
Speaker's Vocal Chords When we speak Audible
Sound Waves are produced that propagate toward
the phones microphone.
The microphone will respond to the sound waves
and convert mechanical energy into electrical energy.
15. Physics In Nuclear Power Plants
Relativity is one reason that mass and energy can be
converted into each other, which is how nuclear power
plants works, and why the sun shines.
16. INTERNET in layman language is nothing but a
group of data which are invisible in nature but can
be seen on computers. Internet is a grid of digital
and analog signals which are modulated and
Demodulated into each other using a MO-DEM.
Internet come under WAVE mechanics because
internet is motion of data in the form of waves.
Physics in Internet
17. 1.REFRIGERATOR WORKS ON THE PRINCIPLES
OF THERMODYNAMICS
2.PRESSURE COOKERS, WASHING MACHINES,
MUSIC SYSTEM, COMPUTERS ALL WORK ON
THE PRINCIPLE OF PHYSICS.
Physics in our daily Life
18. Physics in our daily Life
WHILE YOU ARE READING THIS ARTICLE
THE WORKING OF YOUR EYE IS SIMILAR
TO THE WORKING OF A CAMERA WHICH
AGAIN BELONGS TO PHYSICS.
19. Conclusion
PHYSICS IS THE MOST FUNDAMENTAL OF
THE SCIENCES. PHYSICS IS BEAUTIFUL. PHYSICS
TEACHES US TO THINK. PHYSICS GIVES US A NEW
APPRECIATION OF THE WORLD AROUND US.
