So many my dear friends think that Physics, mathematics and other subjects are so much difficult and to learn this subject we need to do so many efforts, but it's not totally true any subject in education is very much simple you just need to OBSERVE THAT SUBJECT CLEARLY. You will find that subject like your daily playing games.
Here it is *Introduction to physics*
Science has many subjects like physics, mathematics, chemistry, biology, other subjects etc. Let us now understand the subject of 'Physics' through some daily activities. # physics subject #
Physics is something that happens but we can't see it. That is, we hear sound but cannot see sound waves, we see that magnets are attracted to each other but we cannot see that magnetic attraction. In physics we study the natural laws, like an apple falls to the ground and our great scientist see it and we find a discovery called gravity. I mean, we see the apple falling down but we don't see the force of gravity.
Some important points and their example are mentioned below. I hope you understand that easily. We see these example in our daily life.
You will get here # Scope and excitement of physics #
1) Physics teach us law of nature, if we observe natural activities then definitely we understand the physics. So we starts from our scheduled day. At the morning our alarm ringing and we listen this sounds ultimately we wake up at the early morning. So here main point is ' Sound ' which included into the physics subject. These sounds create some sound waves which we listen.

2) So after, at the morning we go for make a tea, for that we boil water. When we observe that hot water creates steam or vapours. So here is main point is Heat. It is also the part of physics. Means heat was dissipated from the water in the form of vapour or steam. These steam we use in many places that is we use it for generating power (For example- electric power, etc) through turbines at a power stations.
3)So now the office time, we take a cars key and go outside. We pull the door of car and seat inside. So here we pull the door means we apply some force to pull the door. The main point is Force. Another example when the car's wheel rotates, their is grip between tyre and the road. That grip create some force, although we stop the car and it slips little bit means we feel some Friction that id also example of force. I hope all understood the force concept.
4) Now we work on the computer. Hence first of all we switch on the button. we give electricity to any device like at current situation we see our mobile / PC etc. It requires electricity , so the these electric or electronic devices are also works on principles of the physics i.e. Electrical Energy .
Hey it's evening coffee time, after sunset we switch on the light. The Light is also the part of physics , we see reflection / deflection of light. Yes it is physics.
So we see some point's i.e. Sound, Heat, Force, Friction, Electricity, Light .
Physics also includes magnetism, gravity, inertia, etc. I hope you all understand the above points which we experiences in our daily life.
