PositionTime graphs  VelocityTime graphs  
direction of motion  sloped up, positive direction sloped down, negative direction 
1st quadrant, positive direction 4th quadrant, negative direction 
instantaneous velocity  slope of line, including + or   height of line, including + or  
instantaneous speed  absolute value of the slope, always positive  absolute value of the height, always positive 
at rest  flat line segments where position remains the same 
flat line segments coincident with the xaxis showing a velocity of zero 
distance traveled  track the  changes in the height of each line  during the time interval requested, always + 
calculate the  areas under each line segment  during the time interval requested, always + 
net displacement  compare the yvalues of the starting and ending points, subtract y_{final}  y_{initial} 
calculate the cumulative areas paying attention to + and  areas 
instantaneous position  height of a line segment at a specific time  cumulative displacement when given a starting position 
average speed  total distance / total time  total distance / total time 
average velocity  net displacement / total time slope of a secant connecting the starting and ending points 
net displacement / total time
