### 5 Matching questions

1. Net Force
2. Motion
3. Point of Reference
4. Machine
5. Speed
1. a movement of objects, people, or animals in many different directions
2. b When a force acts on an object and causes it to move (may be in the same direction or in opposite directions).
3. c the distance an object moves during a certain amount of time (miles per second; mph) Average speed = Distance divided by time
4. d a 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.
5. e the relationship between the person and the moving object

### 5 Multiple choice questions

1. When all the forces act on an object that are balanced and the object doesn't move; no net force.
2. 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. 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.
4. will demonstrate in class
5. the rate when velocity changes over time

### 5 True/False questions

1. Distancea 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.

2. Newton's 2nd Law of MotionWhen 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.

3. Complex Machinea machine that consists of a few parts.

4. NewtonsForce is measured in units called Newtons (not the cookie)

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.
