change in position motion
displacement divided by time velocity
quantity that has magnitude only scalar quantity
change in velocity divided by time acceleration
slowing down in (+) direction or speeding up in (--) direction negative acceleration
the shortest difference between starting point and ending point displacement
velocity and displacement if object returns to where it started zero
positive directions north and east
negative directions south and west
speed up , slow down, change direction 3 ways to be accelerating
don't move or change velocity 2 ways to have zero acceleration
