But trying to describe a complex universe with simple and useful clarifying laws is what physics is all about. So maybe trying to describe the complex activity of what physicists do with a simple and clarifying definition isn’t such a bad idea after all.\nWhat will I learn by studying physics on Khan Academy?\n\nIn physics, we want to explain why objects move around 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 we'll learn how to precisely describe the motion of objects and predict their motion for some special cases.\nWith the ability to precisely describe motion under our belt, we'll learn in Forces and Newton's Laws how the concept of force allows us to explain why objects change their motion.\nWe'll continue mastering and expanding our ability to deal with motion by showing that conservation laws are an alternative way to explain the motion of an object. These conservation laws give constraints on how the motion of a system can change. Conservation of energy will be learned in Work and energy, and conservation of momentum will be learned in Impacts and linear momentum.\nUp to that point we'll have mostly considered objects that are not changing their rotational motion, so in Moments, torque, and angular momentum we'll learn how to describe and explain rotational motion and pick up a new conservation law along the way (conservation of angular momentum).\nAfter this point, we'll deploy what we learned about motion, forces, and conservation laws to analyze how to deal with a variety of new forces and phenomena. We'll learn how to deal with liquids and gases in Fluids and Thermal physics. Then in Electricity and Magnetism we'll learn about two new forces (the electric force and the magnetic force). In Circuits we'll see how electric forces cause current to flow. In Optics we'll investigate the ways in which electromagnetic waves (i.e. light) can bend and reflect. And that's just to name a few.\nBy the end you should have a nice understanding of introductory physics and the mathematical tools physicists use to describe and explain the universe. But no summary can describe all the interesting and powerful aspects of physics. The best way to find out is to jump in and see for yourself.\n\nUser Description: \n\n\nNext Steps: \nIf this is a translation issue, fix it.
