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 ...

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.

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 ...

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 ...

Maxwell’s equations of electromagnetism and the Euler equation top a poll to find the greatest equations of all time. Robert P Crease discusses the results of his reader survey First among equals – ...

In 2017, Roger Guimerà and Marta Sales-Pardo discovered a cause of cell division, the process driving the growth of living beings. But they couldn’t immediately reveal how they learned the answer. The ...
