If gravity pulls everything toward Earth, why don’t satellites crash? Why doesn’t the Moon fall? And why doesn’t the International Space Station drop from the sky?
In this video, we break down the physics of orbit step by step using Newton’s laws, circular motion, and gravitational force. You’ll see how gravity provides the centripetal force needed for orbital motion — and why objects in orbit are actually falling all the time.
We’ll derive the orbital velocity formula and explain what happens if the speed is too slow, just right, or fast enough to escape Earth entirely.
Clear physics. Simple math. Big ideas.
