newtons laws of motion Flashcards
force
push or pull exerted on an object in order to change the motion of the object
motion
a change is position over time
net force
the combination of all forces acting on an object
speed
distance traveled per rate of time
velocity
the speed and direction of an object
acceleration
the rate at which velocity changes over time
newtons first law
and object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside force
newtons second law
force = mass x acceleration
newtons third law
for every action there is an equal but opposite reaction
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
a force that resist motion
mass
the amount of mater in an object
h
