1. Combine the proportions between Mass 1 (m1), Mass 2 (m2) distance (r) into a single proportion to the Force of gravity (Fg)

1. Write the full formula.

1. What happens to the force between the objects if Mass 2 decreases? (increases, decreases, not affected)

1. Explain why varying the second mass had the same effect on the force as varying the first mass.

1. Determine the gravitational constant (G) that will satisfy your units.

1. What direction are the gravitational forces acting on the objects?

1. How does the changing the separation of the objects affect the force between them? (increases, decreases, not affected)

1. What is the relationship between distance and the force of gravity? What happens if the distance is triple between the objects? Half the distance between them?

1. What is the relationship (proportionality) between Mass and force? What happens to the force if you double the mass of the blue object? What happens to the force if you then triple the red object's masses?

1. What is the ratio of the force on the blue object to the force on the red object? What if the mass of the blue one is twice as big as the red object? Explain.
