5. Newton's 3rd Law of Motion
1. a the relationship between the person and the moving object
2. b a machine that consists of a few parts.
3. c When all the forces act on an object that are balanced and the object doesn't move; no net force.
4. d An object in motion will stay in motion unless a force acts on it. An object at rest will stay at rest unless a force acts on it.(No Net Force)
5. e When the 1st object puts a force on a 2nd object, the 2nd object will put a force back on the 1st object as well. Exam: using a hammer to pound a nail, the hammer is creating a force on the nail and the nail is creating a force back on the hammer.

### 5 Multiple choice questions

3. the distance an object moves during a certain amount of time (miles per second; mph) Average speed = Distance divided by time
4. movement of objects, people, or animals in many different directions
5. When 2 objects exert an equal and opposite force on each other.There is no movement!

### 5 True/False questions

1. Worka force that moves an object; no work is done if an object doesn't move. Force X Distance = Work

2. Newton's 2nd Law of Motionthe relationship between mass, acceleration & force. Force = Mass X Acceler.

3. Net Forcea push or pull that acts on an object

4. Powerends of magnets and the North Pole and South Pole: Positive &amp; Negative poles, opposites attract (a + and - or (North &amp; South); like poles repel (push away: South &amp; South, North &amp; North, 2 + or 2-)

5. Joulesends of magnets and the North Pole and South Pole: Positive &amp; Negative poles, opposites attract (a + and - or (North &amp; South); like poles repel (push away: South &amp; South, North &amp; North, 2 + or 2-)
