5. mass
1. a a substance that reduces friction by making surfaces smooth or slippery
2. b a force that opposes motion when an object moves through a fluid (gas or liquid)
3. c the amount of matter in an object, SI unit is kilogram (kg)
4. d a force that causes an object to move in a circular path
5. e a force of attraction between all objects that depends on their masses and the distance between them

### 5 Multiple Choice Questions

1. a force that opposes the motion that occurs when a round object rolls over a surface
2. a force that opposes motion when one solid surface slides over another, caused by microscopic roughness of the two surfaces
3. two or more forces acting on an object that do not cancel each other out, so the object's velocity changes
4. two or more forces acting on an object that cancel each other out to give a net force of zero, and so do not change the object's velocity
5. the combination of all the forces acting on an object
