- Newton's 3rd Law of Motion
- Newton's 2nd Law of Motion
- a 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.
- b a force that pulls everything toward the center of the Earth
- c the force that slows down objects by rubbing against them
- d the relationship between mass, acceleration & force. Force = Mass X Acceler.
- 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
- 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-)
- 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.
- the speed & direction of an object's motion
- a push or pull that acts on an object
- the rate when velocity changes over time
5 True/False questions
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-)
Magnetism → a force that attracts certain metals and other magnets without touching; push or pulls on other objects
Equilibrium → When all the forces act on an object that are balanced and the object doesn't move; no net force.
Complex Machine → a machine that consists of a few parts.
Push/pull → the distance an object moves during a certain amount of time (miles per second; mph) Average speed = Distance divided by time
