### 5 Matching questions

1. Work
2. Newton's 2nd Law of Motion
3. Force
4. Machine
5. Unbalanced Forces
1. a the relationship between mass, acceleration & force. Force = Mass X Acceler.
2. b a push or pull that acts on an object
3. c 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.
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 a force that moves an object; no work is done if an object doesn't move. Force X Distance = Work

### 5 Multiple choice questions

1. movement of objects, people, or animals in many different directions
2. Force is measured in units called Newtons (not the cookie)
3. a machine that consists of a few parts.
4. the speed & direction of an object's motion
5. a machine made of more than one simple machine

### 5 True/False questions

1. Net ForceWhen a force acts on an object and causes it to move (may be in the same direction or in opposite directions).

2. Push/pullwill demonstrate in class

3. Newton's 1st Law of MotionAn 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)

4. Balanced ForcesWhen 2 objects exert an equal and opposite force on each other.There is no movement!

5. Point of ReferenceWhen a force acts on an object and causes it to move (may be in the same direction or in opposite directions).
