Hello,

Physics is a subject which you can always relate with the real life phenomenon. It is the branch of Science which deals with the things happening in the universe.
For example, you can study how the planets revolve, logic behind the motion, you can deeply study about Force and different laws of motion, law of gravitation and many other concepts.
You can actually measure the magnitude of these phenomenon with the help of formulas and derivation given by our great Scientists, such as Issac Newton, Galileo Galilei, Albert Einstein, etc.

Hope this helps.
