5. Pulley
1. a A kind of simple machine consisting of a rope that fits
onto a wheel and used to change the direction of a force
(p. 426)
2. b Machines that only have a few parts - they make it easier
to do work
3. c Energy used when a force moves an object (p. 416)
4. d A contact force that resists the movement of one surface
past another surface (p. 414)
5. e The speed and direction of an object's motion (p. 409)

### 5 Multiple Choice Questions

1. A form of simple machine consisting of a slanted surface
along which objects are easier to push upward than to lift
straight up (p. 429)
2. A push or pull that acts on an object (p. 410)
3. The rate at which work is done (p. 417)
4. A type of simple machine consisting of a bar that turns on
a support called a fulcrum (p. 428)
5. The rate at which the velocity of an object changes over
time (p. 422)

### 5 True/False Questions

1. InertiaThe rate at which work is done (p. 417)

2. MagnetismA force that pushes and pulls on other objects (p. 412)

3. Newton's Third
Law of Motion
An object at rest will stay at rest until another object
acts upon it, and an object moving in a straight line at a
constant speed will continue to move in a straight line at a
constant speed until a net force acts upon it (inertia)

4. MachineA device that changes the direction or the amount of
effort needed to do work (p. 426)

5. SpeedThe rate at which work is done (p. 417)
