|---|---|---|---|---|---|
| Newton'sFirst Law of Motion (The law of Inertia) | an oject at rest will stay at rest and an object in motion will stay in motion Until is acted on by and equal and opposite force
🗑
|
||||
| Newton's Second law of motion | acceleration depends on the mass of an objecr and the force pushing or pulling on the oject.
(F=MxA)-(A=f divided M)
🗑
|

| Newton's Third law of Motion | for every action force there is an egual and opposite reaction force.(comes in pairs)
🗑
|
||||
| acceleration | a change in speed or direction;depends on the mass of an object and the force pudhing or pulling the object.
🗑
|
||||
| average speed | describes the movement for an entire trip by dividing measured distance by measured time.
🗑
|
||||
| force | a push or pull;for example, gravity and friction; can be balanced or unbalanced and can be found mathematically by multiplying mass times acceleration.
🗑
|
||||
| friction | the push or pull that opposes motion when two sliding surfaces are sliding on eachother.
🗑
|
||||
| gravity | a pull that every object exerts on every object and that pulls all things toward earth in the same way.
🗑
|
||||
| inertia | resistance to a change in motion.
🗑
|
||||
| mass | the amount of matter in an object.
🗑
