To define gravity in a way you can understand, gravity means the force of something acting upon something else to bring it down back to the ground.
For example, gravity is what pulls us to the ground when we jump in the air. You can't just jump in the air and stay in place, right?
Another good example is if there was a spaceship directly in between the Earth and the Moon, it would very very very slowly go toward the earth because of its gravitational pull on the spaceship.
Hope this helps! :D
