Gravity is like an invisible string that pulls everything toward Earth, and even keeps planets dancing in space.
Imagine you're holding a balloon. When you let go, it floats up because air is lighter than the balloon. But if you drop a ball, it falls down, that’s gravity at work! Gravity is what makes things fall to the ground when you drop them. It's also why we stay on Earth instead of floating away into space.
How Gravity Works on Earth
Gravity pulls everything toward the center of Earth. That means your feet are pulled toward the ground, and even the air around you feels gravity’s pull. When you jump, gravity brings you back down, like a gentle push from below.
How Gravity Works in Space
In space, gravity still works, but it's different. Planets don’t just float around randomly, they're being pulled by each other! Earth orbits the Sun because the Sun’s gravity pulls us, and Earth’s gravity keeps the Moon circling around us like a space buddy. So even though you feel weightless in space, gravity is still making everything move, it's just not pulling you down to a floor anymore!
Examples
- An apple falls from a tree because Earth pulls it down.
- A ball thrown upward slows down before falling back to the ground.
- A satellite stays in orbit because Earth's gravity keeps it from flying away.
