MouseLab

Freeman Deutsch
Philip M. Sadler
Charles A. Whitney
Stephen T. Engquist
Harvard University

• Study kinematics while looking at the relationship between displacement, acceleration, and velocity
• Helps students see the difference between constant velocity and constant acceleration
• Students can manually sketch graphs and the computer will calculate the other values so the student can see the difference

Physics Plot

Charles Spencer
Ithaca College

• Helps students understand the concepts of plotting graphs
• Allows students to visualize error bars, least square fitting, auto scaling, data manipulation, and function plotting
• Scales can be determined automatically or manually, and log scales can be turned on or off
