A ball is falling through the air. It has just two forces acting on it, its weight and air resistance. Which of the following statements is true?
a. There are only conservative forces acting on the ball.
b. There are only nonconservative forces acting on the ball.
c. There are neither conservative nor nonconservative forces acting on the ball.
d. There are both conservative and nonconservative forces acting on the ball.




All of the following statements are true except one. Which one is false?
a. Work done by a conservative force only depends on the initial and final states.
b. One can never associate a potential energy function with a conservative force.
c. An example of a nonconservative force is friction.
d. Work done by a nonconservative force depends on the path taken.




A point of stable equilibrium
a. has a force that points back toward that point regardless of how you leave it.
b. has a potential energy curve that has a maximum at that point.
c. has a potential energy curve that has a negative slope at that point.
d. is impossible.
