Compares and contrasts net force and head-to-tail diagrams for both constant velocity and constant acceleration situations. Shows how to determine net force from an open head-to-tail diagram.
You should be able to answer the following questions after having viewed this tutorial:
1. What does a head-to-tail diagram look like for a constant velocity situation?
2. What does a head-to-tail diagram look like for a constant acceleration situation?
3. For a properly-scaled diagram, how should the direction of the net force and the direction of the acceleration compare?
