Gravity is an invisible force that pulls objects toward each other. It's what makes things fall down instead of floating away!
How Does Gravity Work?
Think of it like an invisible hug. Every object, even you, has gravity. But the bigger the object, the stronger its gravity.
- Earth's Gravity: Earth is huge, so its gravity is very strong. This strong pull is why you stay on the ground, why balls fall when you drop them, and why the moon orbits us.
- Invisible Pull: You can't see gravity, but you can see what it does. When you jump, gravity pulls you back down to Earth.
- Objects Attract Each Other: All objects with mass attract each other. This is why even small objects have a tiny amount of gravity.
Gravity Explained
Simple Explanation
Gravity is like a magnet, but instead of attracting metal, it attracts everything! The bigger something is, the stronger its pull.
Einstein's View
Albert Einstein, a famous scientist, described gravity a little differently. He said that big objects, like stars or planets, create a curve in space. When smaller objects go near this curve, they are pulled toward the bigger object. It's like rolling a marble around a bowling ball on a trampoline.
Concept | Description |

Gravity | An invisible force that pulls objects toward each other. |
Earth's Gravity | The gravity that keeps us on the ground and makes things fall. |
Einstein's View | Gravity is a curve in space caused by an object with mass. |
Examples of Gravity
- Dropping a ball: It falls to the ground.
- Jumping: You come back down.
- The moon orbiting Earth: Earth's gravity keeps it close.
- Why water in a glass doesn't float: It is being pulled by gravity.
Gravity is everywhere, keeping us all grounded!
