Below you see four different situations and force diagrams for a
circled system object for each situation. The first three involve
an elevator. The fourth involves a box sliding over a smooth
horizontal surface. In each case the initial velocity of the object
is shown.
Consider: How can you make sure the motion of the elevator/box
is consistent with the given force diagram? (Hint: what is the
direction of the sum of the forces in each force diagram?) Explain

ADVANCE STUDY ASSIGNMENT: COULOMB'S LAW PURPOSE of tl of this exercise is to become familiar with the force between electric point charges which is descrbed by Coulomb's law. In particular, we will investigate the force's inverse-square dependence on separation distance between charges. DISCUSSION A basic characteristic of electric charge is that charges exert forces on each other, like charges positive-positive and negative-negative) repel each other while opposite charges (positive- and constitute a Newton's third-law pair; that is, they are equal...
