Bell Ringer: Determining the Angle of a Ramp

Published on 07/14/2010

Activity Overview

Students use precompiled data to calculate the angle of a ramp from the displacement of a ball rolling on the ramp.

Key Steps

  • Image

    Students use a precompiled data set to determine the angle of a ramp. The data set contains position vs. time data for a ball rolling up and down a ramp.

  • Image

    Students fit a parabola to the position vs. time graph. They use the characteristics of the data set (i.e., the vertex of the data points) to predict the equation that best fits the data.

  • Image

    Finally, students use the best-fit equation and the kinematic equations to calculate the angle of the ramp.
