newton's laws of motion 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 ever time.
net force
the combination of all the forces acting on an object
speed
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.
newton’s first law
an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside force.
newton’s second law
force = mass x acceleration
newton’s 3 law
for every action there it an equal but opposite reaction.
inertia
the tendecy of an object 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 resists motion
mass
the amount of matter in an object.
gravity
an attractive that exists between all abjects that have mass.
