Transcript of Physics in our lives
But then was advent of a thing that revolutionized our lives…………………….
But ……………What ?????????????????
Humans developed an awesome brain
which fed on mysteries of nature!!!!!!!
With it developed a VISION
TO see beyond the world…..
Great Names In Physics:::Maxwell Rutherford Isaac Newton
Galileo Einstein Madam Curie
Enricofermi
J J Thomson Mulliken
Where Do we See Physics in Our life and How does it affect us!!
Why before the water boil, it will produce a Why before the water boil, it will produce a ““woo-woo” sound? woo-woo” sound? It is because the water particles at the bottom of the kettle boil first. When It is because the water particles at the bottom of the kettle boil first. When they are heated at about 100°C, they are heated at about 100°C, they become water vapors and rise. However, they become water vapors and rise. However, the water particles above are yet to boil. When the vapors are the water particles above are yet to boil. When the vapors are in contract with the water particles above, they change back to the waterin contract with the water particles above, they change back to the water droplets immediately. The expansion and contraction of water particles bringdroplets immediately. The expansion and contraction of water particles bring about vibration of water. The upward movement of the gas bubbles produceabout vibration of water. The upward movement of the gas bubbles produce the “woo-woo” sound.On the other hand, once all the water particles boil atthe “woo-woo” sound.On the other hand, once all the water particles boil at 100°C, the gas bubbles can get to the surface stably. 100°C, the gas bubbles can get to the surface stably. No contraction would occur and hence no sound will be produceNo contraction would occur and hence no sound will be produce
The use of speakerThe use of speaker A speaker uses electromagnets to transform A speaker uses electromagnets to transform electric current into sound. Electric current and electric current into sound. Electric current and Magnetic force have a close relationship. WhenMagnetic force have a close relationship. When an electric current is passed through the wire, an electric current is passed through the wire, a magnetic field would be produced.a magnetic field would be produced.

A lightning rod is not used to block lightning, A lightning rod is not used to block lightning, but to provide a safe but to provide a safe path for the charges in the cloud to neutralize path for the charges in the cloud to neutralize with those on the groundwith those on the ground, thus it could protect the building from being, thus it could protect the building from being damaged by lightningdamaged by lightning..
Oh !! How could I forget!
Mass is a physical term….
I’d eat a lott of yummy bread to gain mass!
Your mass is the amount of material
that your body contains.
How can you gain mass?

Hey !!! Some of you wear this ,its also a solution from PHYSICS
Physics Explains it!!
This tooIt explains why do we feel lighter in downward motion of lift
and heavier in upward Solar Eclipse which were once considered to be a time when ‘rahu’ puts Sun in his mouth
Though funny but its true!!!!!!!!!!!!!!!!!!!!!
And Now Physics is in search of the Truth :the GOD So Scientists had laid experiments with machines like LHC
Large Hardon Collider
Ever heard about it?????????? IF no…… Have a look!!!!!
