Which graph shows acceleration?
A graph of position (meters) versus time (seconds) has a straight line running from 0 seconds 0 meters upward.
A graph of position (meters) versus time (seconds) has a concave line running from 0 seconds 0 meters upward.
A graph of position (meters) versus time (seconds) has a straight line running from 0 seconds positive number of meters downward to some later time 0 meters.
