Why does a projectile follow a perfect curve through the air? 🎯 This video explains projectile motion by deriving the parabolic trajectory, using kinematics and constant acceleration to show how ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

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.

The renowned cosmologist wants to make the ideas of modern physics accessible to anyone who’s willing to do a bit of extra thinking. The following is an excerpt from The Biggest Ideas in the Universe: ...

Equations are the bedrock of science, expressing how numbers or physical properties relate at a fundamental level. Without equations, most of our technology would never have been invented. We may have ...

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 ...

E = mc 2 is probably the most recognized physics equation among the general public, beating out Newton's Second Law of motion, F = ma. Despite that recognition by the outside world, E = mc 2 is hardly ...
