speed
the rate of change of position (distance per time or d/t)
velocity
speed with direction
acceleration
the rate of change of velocity (velocity per time)
mass
quantity of matter (inertia)
weight
gravitational force
inertia
tendency to continue at rest or with constant velocity (mass or laziness)

opposes motion
force
a push or pull
Newton's First Law
, Law of Inertia

100 N
gravity
attraction between any two objects
acceleration due to gravity on earth
9.81 m/s²
centripetal force
directed toward center, causes circular motion
