Khan Academy offers free, world-class education in physics, covering forces and motion topics.

Physics is built on a foundation of math and it seeks to explain all phenomena in the universe. It forms the basis for other sciences like chemistry and biology. Physics uses simple yet elegant …

Let's explore the mysteries of light and electricity. From how light reflects, to correcting defects in our eyes. From understanding charges to lighting up cities. From Newton's prism to Faraday's …

Electric force and electric field are vector quantities (they have magnitude and direction). Electric potential turns out to be a scalar quantity (magnitude only), a nice simplification.

Our mission is to provide a free, world-class education to anyone, anywhere.

Learn physics using videos, articles, and NGSS-aligned practice exercises. Explore the fundamentals of motion and forces, non-contact interactions, energy, and waves.
