What makes an apple fall from a tree, but stops the Moon from crashing into Earth? The answer is a powerful force that affects everything in the universe—gravity! Whether you’re jumping, throwing a ball, or watching the stars, gravity is always pulling something towards something else.

In this topic, we’ll explore gravity from falling apples to orbiting planets, starting from the simple fall of an apple to the massive orbits of planets and moons. We’ll look at famous discoveries, fascinating facts, and strange space science. By the end, you’ll know exactly why we don’t float away into space—and why planets keep circling the Sun!
