Phyics Flashcards
Force
A push or a pull exerted on an object to change the motion of the object
Motion
Change in position over time
net force
the combination of all the forces acting on a 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
an object 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 tendacy 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 upon the object
friction
a force that resits motion
mass
the amount of matter in an object
gravity
an attractive force that exists between all objects that have mass.
