Features over 30 inquiry based labs covering the core topic areas of mechanics, electricity and magnetism, optics, thermodynamics and more.

Speed and Velocity

Lab Summary

Use a motion sensor to test predictions of how the speed and velocity of a cart will differ.

Theory

This experiment highlights the similarities and differences between the concepts of speed and velocity. Students predict how the speed and velocity of a cart will differ, and then test their predictions by analyzing graphs generated using a motion sensor.

  • Method

    Students gain experience conducting the following procedures:

    • Predicting how a velocity versus time and speed versus time graph will look for a cart travelling down a track and back.
    • Assembling the equipment using a dynamics cart and track, as well as a motion sensor.
    • Measuring the actual speed and velocity using the motion sensor as the cart travels along a track.
    • Comparing the predicted graphs to the actual graphs.
