newtons laws of motion vocabulary Flashcards
force
a push or a pull exerted 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 forces acting on an object
speed
distance travel 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 remain at rest and an object in motion will remain in motion unless acted upon by outside force.
newtons second law
force = mass x acceleration
newtons third law
for every action there is an equal but opposite reactions.
inertia
The tendency of an object to resist being move or, to resist in changed in speed or direction until and outside force acts on the object.
friction
a force that resists motion
mass
the amount of matter in an object.
