### 5 Matching questions

1. Newton's 3rd Law of Motion
2. Push/pull
3. Gravity
4. Equilibrium
5. Electricity
1. a a force that pulls everything toward the center of the Earth
2. b When all the forces act on an object that are balanced and the object doesn't move; no net force.
3. c will demonstrate in class
4. d the flow of electrically charged particles, electrons, between objects.
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

1. a force that moves an object; no work is done if an object doesn't move. Force X Distance = Work
2. the speed & direction of an object's motion
3. the force that slows down objects by rubbing against them
4. 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. When 1 object exerts more force on another object and movement occurs. Forces may be in the same direction or opposite directions, but there is movement. There is a Net Force.

### 5 True/False questions

1. 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-)

2. Machinea tool or device that makes work easier by changing the direction or the amount of force needed to move an object; DOES NOT make less work.

3. 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-)

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

5. Balanced ForcesWhen 1 object exerts more force on another object and movement occurs. Forces may be in the same direction or opposite directions, but there is movement. There is a Net Force.
