(b) Your effort is reduced, and your lesser strength becomes sufficient.
(c) Your effort is reduced so you can take advantage of your greater strength.
(d) Your effort is reduced, but your strength has to be increased.

2. What does a driving force initiate?
(a) Work.
(b) Movement.
(c) Electron activity.
(d) Inertia.

3. What is an example of a second-class lever?
(a) A clock.
(b) A crane.
(c) An engine block system.
(d) A nutcracker.

4. What do compound levers contain?
(a) A single fulcrum and two points of force and two of load.
(b) Two fulcrums and one point of force and load.
(c) Two fulcrums and two points of force and two of load.
(d) No fulcrum but two points of force and two of load.

5. What does the Mechanics of Movement explore?
(a) How the conservation of energy plays into movement, force, and effort.
(b) How pulleys ultimately lose energy that can never be regained.
(c) How the movement of anything can be either a net gain or net loss of energy.
(d) How pulleys can create energy.
