- Newton's 1st Law of Motion
- Newton's 3rd Law of Motion
- a 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)
- b a force that pulls everything toward the center of the Earth
- 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 the speed & direction of an object's motion
- e Work in measured in units called Joules (not the ones I wear)
5 Multiple Choice Questions
- 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.
- 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.
- a force that moves an object; no work is done if an object doesn't move. Force X Distance = Work
- a force that attracts certain metals and other magnets without touching; push or pulls on other objects
- the force that slows down objects by rubbing against them
5 True/False Questions
Net Force → When a force acts on an object and causes it to move (may be in the same direction or in opposite directions).
Distance → Force is measured in units called Newtons (not the cookie)
Speed → the distance an object moves during a certain amount of time (miles per second; mph) Average speed = Distance divided by time
Inertia → Force is measured in units called Newtons (not the cookie)
Power → work is done in a certain time. Work divided by time = power; measured in Watts
