1) Consider the four free body diagrams. Free-body diagrams are used to
show the magnitude and direction of all forces acting on an object in a
given situation. Do any of the free body diagrams indicate motion? If
yes, which one(s).

A). No. In all four free body diagrams the forces are
balanced.
B). Yes. In B the book is slowing down because of the
friction force opposing motion.
C). Yes. In the two forces are unbalanced. The upward
force is greater than the force of gravity so the object
moves upward
D). Yes. In B and D. In both cases, forces are unbalanced.
In B. there is a net force to the left; in D there is a net
force upward
