The distance is the absolute value of the displacement E x a m p le : R o u n d t r ip ( 1 ) ! Distance between Des Moines, Iowa, and Iowa City, is listed as 113.5 miles or 182.6 km • Straight line, to very good approximation ! = !x ! Distance is always positive (or 0) ! Distance is a scalar, displacement a vector ! Question: • If we take a round trip Des Moines – Iowa City – Des Moines, what is the total distance and displacement for this trip?
