newtons laws of motion vocabulary Flashcards
force
a push or pull on an object in order to change the motion of the object
motion
a change in position over time
net force
the combination of all the` forces action on an object
distance traveled per rate of time
speed= distance/time
velocity
the speed and direction of an object
acceleration
the rate at which velocity changes over time
newtons first law
an object at rest will remian at rest and object in motion will remain in motion unless acted upon by an outside force
newstons second law
force = mass x acceleration
newtons thrid law
for every action there is an equal but oppisite reactio
inertia
the tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object
friction
aforce that resist motion
mass
the amount of matter in an object
