newtons law 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 over time.
net force
the combination of all the forces on an object
speed
distance traveled per rate 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 abject at rest will ramain at rest nad object in motion will remain
newton’s second law
force= mass x acceleration.
newton’s third law
for every action there is an equal opposite reaction
Inertia
the tendency of an object to resist being moved, or if the object is moving, to resit 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 force that exists between all objects that have mass
