What is physics?
To be dependable, it’s really awkward to define incisively what physics is. For one, physics keeps changing as we progress and make new discoveries. Newfangled theories don’t but bring freshly replies. They also create new questions that might not have an even made sense when regarded from within the late theory of cathartics. This makes physics exciting and mattering to, but it also impels attempts at defining physics into generalizations approximately what physical science has constituted instead of what it might be at some point in the future.
That said, definitions are useful. So, if it’s a definition you want, it’s a definition you’ll get. For the most part, physicists are trying to do the following:
- Precisely define the most fundamental mensurable amounts inch the universe (e.g., velocity, electric field, kinetic energy). The effort to find the most key verbal description of the universe is a quest that has historically always been a big part of physics, as can be seen in the comic image below.
- Find relationships between those cardinal appraised amounts (for instance., Newton’s Laws, conservation of energy, special relativity). These patterns and correlational statistics* are carried exploitation words, equations, graphs, charts, diagrams, models, and any other means that allow us to express a relationship in a way that we as humans can better understand and function.
All right, and so boiling cathartics down to just two things is admittedly a bit of a gross simplification and glosses over some of the finer points of what physicists do and how they do it. But assaying to discover a complex universe with simple and useful clarifying laws is what natural philosophy is whole astir. In order maybe attempting to depict the complex activity of what physicists do with a simple and clarifying definition isn’t such a bad idea after all.
What will I learn by studying physics at LearnPhysics.Org?
In aperients, we want to excuse why objects travel the way they do. However, it would be hard to explain motion if we didn’t know how to describe motion.
So first, in the topics One-dimensional motion and Two-dimensional motion, advantageously con how to precisely describe the motion of objects and predict their motion for some special casings.
