### 5 Matching Questions

1. Unbalanced Forces
2. Velocity
3. Newton's 2nd Law of Motion
4. Friction
5. Electricity
1. a the force that slows down objects by rubbing against them
2. b 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.
3. c the flow of electrically charged particles, electrons, between objects.
4. d the speed & direction of an object's motion
5. e the relationship between mass, acceleration & force. Force = Mass X Acceler.

### 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. 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)
3. When a force acts on an object and causes it to move (may be in the same direction or in opposite directions).
4. 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. a machine that consists of a few parts.

### 5 True/False Questions

1. InertiaForce is measured in units called Newtons (not the cookie)

2. Forcea push or pull that acts on an object

3. Powerwork is done in a certain time. Work divided by time = power; measured in Watts

4. 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.

5. 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.
