Gravity is like a giant invisible string that pulls planets toward the sun. When a planet moves fast enough, it doesn’t fall into the sun, it keeps going around and around, just like when you swing on a rope.
Why It Works
Imagine you're holding a ball on a string and spinning in circles. If you let go, the ball would fly off in a straight line. But gravity acts like that string: it tugs the planet toward the sun while the planet keeps moving forward, making it orbit instead of falling down.
Examples
- Gravity keeps Earth in orbit, just like a ball on a string stays in circular motion.
- If gravity disappeared, we’d float away into space, or fall straight into the sun!
- Planets move sideways as they’re pulled toward the sun, creating an orbital path.
