Gravity is a force of attraction between any two masses. It’s the force that causes an apple to fall from a tree, and it’s also what keeps us stuck to Earth.
Gravity has different effects on different objects depending on their mass. The stronger an object is attracted to another mass, the more gravity it feels.
For example, a large boulder would be very heavy and would fall quickly under Earth’s gravity, while a feather would be light and would float in the air with little effort from gravity.
Gravity can be negative when there are more than two objects involved in the attraction. For example, if you were standing on the surface of Jupiter and were pulled towards its center by its strong gravitational pull, you would feel twice as much weight as you do on Earth because there is twice as much mass pulling you down!
