Write 3 things you know about Gravity
3 of the Following:
-A force that pulls objects toward each other.
-On Earth, the force that pulls everything towards the center of the Earth
-The greater an object's mass, the greater it's gravity
-The force that keeps the Moon in orbit around the Earth.
-The force, due to the effect of the Moon, that is responsible for tides on Earth.

Why did the Ancient Greeks call the planets 'wandering stars'?
