Gravity is the force that pulls everything towards each other. The bigger something is, the stronger its gravity. That's why the Earth's gravity keeps us on the ground! Gravity also makes objects fall down, not up. It's an invisible force that affects everything around us, from apples falling from trees to planets orbiting the sun. Think of it like an invisible string connecting everything!
Match the word to its definition:
| Word | Definition |
|---|---|
| 1. Mass | A. The force that pulls objects together. |
| 2. Gravity | B. The amount of matter in an object. |
| 3. Weight | C. A measure of how strongly gravity pulls on an object. |
| 4. Force | D. An interaction that, when unopposed, will change the motion of an object. |
| 5. Orbit | E. The curved path of an object around a star, planet, or moon. |
