Explore how quadratic drag influences the motion of objects moving in a straight line. In this video, we break down the physics behind resistive forces that increase with the square of velocity, ...

Learn how to perform numerical calculations using projectile motion in this physics tutorial! This video guides you step by step through solving problems involving velocity, angle, and displacement, ...

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 ...

Did you know that, at a certain point on a moving wheel... there's no motion? Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right?

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.
