Method II: Acceleration from the velocity versus time graph.

This method is similar to using the position vs. time graph, but instead uses the velocity versus time graph.

• Start with a graph of the velocity vs. time graph (this should be a straight line for constant acceleration).
• Add the trendline, but this time tell Excel to make it a linear trendline. It should then look something like this:
• 
• Where in this equation, y should really be v and x should again be t. Again we can "match up" the equation to one of the kinematic equations:
• 
• So, with this method, the acceleration is 2.806 m/s^2
