Physics is defined as a natural science which studies the dynamics of matter, energy and physical forces. Advanced physics relies upon Calculus to mathematically represent motion and acceleration. Physics is the underlying foundation which explains processes in Chemistry.
So what is Physics anyway? Simply put Physics is the study of energy. Okay that's a short answer, what does that mean, the study of energy? Well we can break down Physics into several units one of them is motion, you're familiar with motion, concepts like speed and velocity. Forces, physical forces include things like gravity and friction. Physical forces are energies also carried in the form of waves and when we talk about waves we're typically talking about things like sound waves and light waves.
Other topics in Physics include electricity and magnetism a lot of people understand what electricity is we all use electricity but it's very few people understand how electricity actually works, so we'll study currents, power in form of waltz and how electrical current can be used to create magnetic fields. Another thing we're going to study in Physics is atomic and nuclear Physics understanding the atom Einstein's theory or relativity and also nuclear reactions and nuclear fusion and how they can release huge amounts of energy. So see these are some of the topics that are covered in a Physics course.
