- Balanced Forces
- Unbalanced Forces
- Point of Reference
- Newton's 3rd Law of Motion
- a 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.
- b the relationship between the person and the moving object
- c 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.
- d When 2 objects exert an equal and opposite force on each other.There is no movement!
- e When all the forces act on an object that are balanced and the object doesn't move; no net force.
5 Multiple Choice Questions
- the force that slows down objects by rubbing against them
- the speed & direction of an object's motion
- the flow of electrically charged particles, electrons, between objects.
- a force that attracts certain metals and other magnets without touching; push or pulls on other objects
- a machine made of more than one simple machine
5 True/False Questions
Poles → 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-)
Inertia → Force is measured in units called Newtons (not the cookie)
Gravity → a force that pulls everything toward the center of the Earth
Machine → 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.
Newton's 1st Law of Motion → 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)
