Shini Somara introduces us to the ideas of motion in a straight line. In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

A perpetual motion machine is (as the name implies) a machine that moves perpetually; it never stops. Ever. So if you created one today and set it going, it would keep on going until the Big Freeze.

In just over a day, a powerful computer program accomplished a feat that took physicists centuries to complete: extrapolating the laws of motion from a pendulum's swings. Developed by Cornell ...
