significant figures (p17)
those digits in a measurement that are known with certainty plus the first digit that is uncertain
displacement (p41)
the change in position of an object
average velocity (p43)
the total displacement divided by the time interval during which the displacement occured
instantaneous velocity (p46)
the velocity of an object at some instant or at a specific point in the object's path
acceleration (p48)
the rate at which velocity changes over time; an object ~ if its speed, direction, or both change
