Physics does not have a specific definition but it can be defined as a branch of science that deals with the study of matter and its relation to Energy.
Matter is anything that has mass and occupies space while Energy is the ability to do work.
Physics is a subject that aim to help us understand the nature of the universe through its branches.
The branches are Mechanics, Thermodynamics, Optics, Acoustic, Electromagnetism, Relativity and Quantum Physics.
It has the theory aspect, calculation aspect and also practical aspect.
We are going to be discussing on the topics under these branches in a simplified way.
One piece of advice: Physics at the outset is philosophy, at the core is mathematics and in between is symbolic. Do not take something too seriously.
Let's move straight into the topics. See you there.
