A) Discuss Newton's Universal Law of Gravity (NULG).

a. What is required for there to be gravity?

b. On what does gravity depend?

c. What is the difference, if any, among "Force of Gravity", "G", and "g"?

B) Consider a book dropped from rest from the ceiling onto the floor. Describe the motion of the book.

a. Does it travel at the same speed the entire time?

b. Does it travel with the same velocity the entire time?

c. Does it travel with the same acceleration the entire time?

d. Does it have the same forces acting on it the entire time?

e. Do any of the forces change in strength during the fall or do the forces remain the same strength the entire time?

Explain your responses.

Consider the same three situations as last week; however, consider what would occur if these experiment were performed on the Moon instead of planet Earth.

The three situations are:

1.) Hold the textbook and sheet of paper side by side.

2.) Place the sheet of paper directly beneath and touching the textbook.

3.) Place the sheet of paper directly on top of and touching the textbook.

For each thought experiment you drop them both at the same time and predict which one will travel with the faster motion. Attempt to defend your predictions using the concepts of Newton's Second Law, Inertia, Gravity, and Forces. Also include comparisons to the Earth situations.
