The solar system stays balanced because gravity pulls things together and motion keeps them from crashing into each other.
Imagine you're on a swing. The rope (like gravity) pulls you down, but your motion (like swinging back and forth) keeps you from just falling to the ground. That’s kind of how planets work!
Gravity is like a big invisible string
Motion keeps things from crashing
If you're on a swing and you stop swinging, you'll eventually fall down. Planets are like that too, if they stopped moving, they’d crash into the Sun. But because they keep moving, they stay in their orbits instead of spiraling in or flying away.
So gravity and motion work together, one pulls, the other keeps things going, and that’s how our solar system stays balanced!
Examples
- Imagine playing catch with a friend, that's how the sun and planets move in space.
