- a the relationship between the person and the moving object
- b a machine that consists of a few parts.
- c When all the forces act on an object that are balanced and the object doesn't move; no net force.
- 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)
- 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.

- how far an object moves
- a force that attracts certain metals and other magnets without touching; push or pulls on other objects
- the distance an object moves during a certain amount of time (miles per second; mph) Average speed = Distance divided by time
- movement of objects, people, or animals in many different directions
- When 2 objects exert an equal and opposite force on each other.There is no movement!
5 True/False questions
Work → a force that moves an object; no work is done if an object doesn't move. Force X Distance = Work
Newton's 2nd Law of Motion → the relationship between mass, acceleration & force. Force = Mass X Acceler.
Net Force → a push or pull that acts on an object
Power → ends of magnets and the North Pole and South Pole: Positive & Negative poles, opposites attract (a + and - or (North & South); like poles repel (push away: South & South, North & North, 2 + or 2-)
Joules → ends of magnets and the North Pole and South Pole: Positive & Negative poles, opposites attract (a + and - or (North & South); like poles repel (push away: South & South, North & North, 2 + or 2-)
