This lesson is a physics application of PocketLab that allows students to determine the radius of curvature of a gradual turn on a street. A PocketLab mounted on the dashboard of a car records both the angular velocity and the centripetal acceleration of the car as it moves at a nearly constant speed around the curve. All of the required data for an example problem are contained in files attached to this lesson. Alternately, students can collect their own data. If the latter approach is...
