Describe how Sir Isaac Newton “discovered” gravity
Tell that the shape of the earth is a sphere
Recall gravitational force as the force that causes two objects to move toward each other
Understand the difference between mass and weight
Support an argument that the gravitational force exerted by Earth on objects is directed down.
