Force & Motion: Constant Velocity

You are going to face several challenges with respect to position and velocity.

Constant Velocity

Students will see a change in the slope of the graph as mass is changed, enabling them to compare two different but constant velocities. Enlarge graph.

Lab Summary:

Students will use the Motion Sensor to come to an understanding of the relationship between position and velocity.

First, students will qualitatively examine a plot of position versus time. Next, they will establish the meaning of the plot's slope. In turn, they will investigate the plot of velocity versus time. Finally, the students will establish the relationship of the slope of position versus time and relationship to the average or mean velocity established in the graph of velocity versus time.
