Physics

Physics is the study of matter, motion, energy, and force. Here, you can browse videos, articles, and exercises by topic.

Videos covering a wide range of physics topics

Hundreds of free videos have been made available by the world’s top universities, and they feature some of the leading physicists of our era. This site has compiled just a fraction of these in a kind of “guide to the cosmos” that will give you a basic overview of the key concepts in physics.

Physics simulations animated in real time--interact with them by dragging objects or changing parameters like gravity.

Over 200 simulations for introductory physics

Written by a high school physics teacher, The Physics Classroom is an online, free to use physics website developed primarily for beginning physics students and their teachers.

Physics Central communicates the excitement and importance of physics to its readers. Part of the American Physical Society site.

A collection of more than 600 websites that you can search or browse to explore physics on your own. It's also a biweekly online magazine, with archives containing more than 55 selected physics images.

This site is part of the World of Science , an online encyclopedia created by Eric Weisstein, a Ph.D. in planetary science, "with assistance from the physics and internet communities."

The resource allows users to design their own roller coaster, and along the way they will learn about the laws of gravity, pendulums, and kinetic energy. This resource contains interactive graphics and a glossary terms.

Explore TED's talks and playlists on physics.

Many people come to the subject of physics with a bit of fear. But as you begin your exploration of this broad-ranging subject, you may soon come to realize that physics plays a much larger role in your life than you first thought, no matter your life goals or career choice.

Galaxies are as immense as atoms are small, yet the same laws of physics describe both, along with all the rest of nature—an indication of the underlying unity in the universe. The laws of physics are surprisingly few, implying an underlying simplicity to nature’s apparent complexity. In this text, you learn about the laws of physics.
