ROLE OF PHYSICS AND ITS LAWS IN OUR LIFE

Everything, what is going and what is not going too, is because of certain factors behind it. Physics is there in every single moment. Be it rotation and revolution of earth around the sun or bending of the bike towards earth while crossing a curved road at a high speed. Physics is involved everywhere. Let us know this physics a little basic to understand well that what is going around us.


WHAT MIRROR SAYS
There are 3 types of mirrors. Convex, concave and plane mirror.
Plane mirror form same size of image as that of the object.
Concave mirror form image bigger than the object.
Convex mirror form the image smaller than the object size that’s the whole big framed background appears on your small sized mirror screen of your vehicle.

LIGHT CHANGES ITS ATTITUDE WHEN IT FEELS A CHANGE IN SURROUNDING
Yes, this is true. The light changes its behaviour when passes into a different media for example – travelling from air into water. It does so by bending. This is called refraction. The diamond is cut into multiple edges and curve to produce multiple refraction or bending of light inside the diamond piece and this is the reason behind its beautiful attractive shine.
Twinkle twinkle little stars….. But why stars twinkle?  Twinkling of stars is due to multiple refraction (bending) of starlight passing from different layers of the atmosphere.
You see the sun, but sun is not there…What this statement is about? Answer is due to refraction. It happens at the time of sunrise and sunset. The is visible to us about 2 minutes 2 minutes before the actual sunrise and 2 minutes after the actual sunset. Knowing this ,now you could make an excuse of waking up 2 minutes late.

GRAVITY ON MOON
The weight of any object becomes 1/6th on the moon than it is on earth. This happens due the fact that the acceleration which the earth attracts falling objects becomes 1/6th on the earth. Imagine a person weighing 90kg on earth if go to moon would definitely feel happy as he would be weighing only 15kg on moon. How light is that even without following a diet plan.

POWER OF  YOUR HOUSE
Although the unit of energy that you consume in terms of electricity is Joule and power is written in terms of watt. But this unit becomes so small in front of heavy appliances of your home such as television, AC, refrigerator etc. So the total energy consumed is calculated in terms of bigger units such as
KWh (kilo watt hour), MGh (megawatt hour) or GWh (gigawatt hour) In British engineering system bigger unit of power is Horse power.
