Lab 2: Graph Matching

Question 1) Positive Slope - Speed is positive 0 Slope - Object is at rest Negative Slope - Negative speed

If the line crosses the x axis it would be going negative distance, or before its starting point. This did not happen during the lab, since the camera isn't able to track what is behind it.

Question 2) Positive Slope - The object is accelerating 0 Slope - Velocity/speed is at a constant acceleration Negative Slope -The object is deccelerating

When the line crosses the x axis of a velocity time graph, it has slowed down to 0 speed and changed direction. This did happen since it was necessary to change direction.
