location relative to the origin (x or y)
velocity
speed & direction
acceleration
how velocity is changing. object is speeding up, speeding down, or constant speed.
+position
right or above
-position
left or below
displacement
change in x = final position - initial position

+velocity
moving to the right or up
- velocity
