Gravity
Ages 6-10Beginner
Gravity is a pulling force. It pulls everything toward the ground. That's why when you drop a ball, it falls down instead of going up!
⚡ Fun Fact:Legend says that Isaac Newton got the idea to study gravity when he saw an apple fall from a tree. He asked: why does the apple always fall down?
Gravity depends on how heavy (massive) something is. The heavier something is, the stronger its gravitational pull. Earth's gravity keeps us on the ground and makes things fall.
