Best Sites to Learn Physics for Free

Physics is one of those subjects that anybody can learn. It doesn’t matter what your background is, who you are, where you came from – anybody can learn physics with the right instruction. If you understood the rules of physics, you understood how the world worked, you can make a prediction about something that was gonna happen in the future! And that is the real power to learn physics.

Physics is awesome and interesting because it asks the one question no other [physical] science does: “how?”

Take, for instance, a moving car. A physicist, sees a moving car and wonders “how can the car move?” “What is providing a forward motion? How are the wheels even able to turn?” And, on the other end of the spectrum. Well, the ultimate goal of physics is to understand the universe around us.

This ranges from tiny, inter-molecular particles, to huge things like entire solar systems. Physics argues that there must exist fundamental rules that govern the how of everything around us, and it is physicists’ job to find out what those rules are and apply formulas to them. It is really is fascinating how much we already know, yet mindboggling how much we don’t. Such simple mechanics, such as Newton’s famous “force equals mass times acceleration” equation can help scientists understand the basic motion of nearly anything.

What is Physics? Overview, Definitions & terminologies

Physics is second only to mathematics in the purity of its principles. Physics describes how the natural world works through applied mathematical formulas. It deals with the fundamental forces of the universe and how they interact with matter looking at everything from galaxies and planets to atoms and quarks and everything in between. All other natural sciences stem from physics. Chemistry is essentially applied physics and biology is essentially applied chemistry. Physics theory is responsible for the breakthroughs in electronics that precipitate advances in modern computers and electronic media.

How Maths relates to Physics?

Maths is basically the language of the universe, which means it’s the language of physics. You have to understand maths in order to understand physics for any serious level of study. Actually, make that vectors and matrices are important. They’re tied up in the field of linear algebra, you know and that becomes important as you go into higher levels of physics and other fields, as does, for example, group theory.

But if you’re going to go for a more fundamental aspect of maths I definitely say that algebra is a super important one to understand, because that’s the way in which most physical laws are expressed. You know you you have to nail those early maths classes, and I think algebra, in particular, to stand much of a chance of really engaging with physics.

Basically, you should be taking all of your maths classes seriously. Some people complain that you have to do so much maths in order to do physics, when the fact of the matter is, if you don’t like doing maths, you’re not gonna like doing physics. Physics is basically maths! A physics degree is, effectively, a maths degree just with a lot of applications. Where can we Learn Physics?
