newtons laws of motion Flashcards
force
a push or 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 acting on an object
speed
distance traveled per rate of time
speed= distance/time
volocity
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 object in motion will remain in motion unless acted upon by an outside force
newtons second law
force = mass x acceleration
newtns third law
for every action there is an equal but opposite action
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 matter in an object
gravity
an attractive force that exist between all objects that have mass
