📚 Topic Summary
Gravity is the force that pulls everything in the universe towards each other. The bigger something is, the stronger its gravity. That's why the Earth's gravity keeps us on the ground! It's also why things fall down instead of floating up. Gravity affects everything, from apples falling from trees to the planets orbiting the Sun.
