Graphing Velocity

• When graphing velocity, we use the distance-time graph

  
• Notice that in the graph (attached) between points A and B, the object travels at a constant speed, and from B to C it has stopped.

  
• Between points C and D, the direction changed.

  
• If the slope is positive, then the object is moving forward; if negative, backward.
• From point A to B, the object was traveling in one direction away from the starting point.

  
• From points C to D, the line goes down from 50 meters to 40 meters and so on, until it returns to where it started
