define distance
total length of travel
define displacement
length measured between the staring and ending points; is a vector
define scalar
measurement w/o direction; CANNOT be negative
define position
able to be located in space
define velocity
rate at which displacement occurs
define speed
the rate at which distance is covered
speed equation
d(distance)/change in time
velocity equation
change in X/change in time
displacement equation
delta X=X-X naught
