Physics In Day To Day Life

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. 

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.

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.

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.

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.

1St Law Of Motion

An object at rest stays at rest, unless an external, unbalance force acts on it.

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. 

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.

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.

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.

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.

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

1.REFRIGERATOR WORKS ON THE PRINCIPLES OF THERMODYNAMICS 2.PRESSURE COOKERS, WASHING MACHINES, MUSIC SYSTEM, COMPUTERS ALL WORK ON THE PRINCIPLE OF PHYSICS.

WHILE YOU ARE READING THIS ARTICLE THE WORKING OF YOUR EYE IS SIMILAR TO THE WORKING OF A CAMERA WHICH AGAIN BELONGS TO PHYSICS.

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.

That’s All
