Learn the principles of projectile motion by analyzing how far a ball travels when launched from a table. This tutorial breaks down the equations, calculations, and reasoning step by step, helping ...

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.

When a student first learns how a simple equation can explain the motion of planets or the behaviour of light, it sparks more ...

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 ...

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 ...
