Gravity is like an invisible string that pulls things together. The Sun uses gravity to keep Earth and other planets in their orbits, just like how your hand can keep a ball from rolling away.
Like a Game of Catch
Think of the Solar System as a game of catch. The Sun throws out its energy, and the planets catch it, gravity keeps them from flying off into space. It’s like being on a swing: you go up high, but gravity brings you back down.
Examples
- If you let go of a ball on Earth, it falls down because of gravity.
- When you swing around on a swing, you stay up because of the balance between your motion and gravity pulling you back.
- A planet like Mars stays in its orbit because the Sun’s gravity pulls it in, but Mars keeps moving sideways so it doesn’t crash into the Sun.
