Method:

Use a Motion Sensor to measure the motion of a cart during a collision and use a Force Sensor to measure the force during the collision. Compare the change in momentum of the cart to the impulse.

Here's What You Need:

Required for computer-based lab:

(See lab download for Xplorer GLX-based lab requirements, which may differ)

Probeware

• PASPORT Motion Sensor (PS-2103A)
• PASPORT Force Sensor (PS-2104)
• Xplorer GLX Graphing Datalogger (PS-2002)
  (or alternate PASPORT interface -- see other options )

Other Materials

• PAScar Dynamics System, 1.2 m (ME-6955)

Lab Manual:

The computer-based activity is included in Explorations in Physics (PS-2810). The Xplorer GLX-based lab is included in Physics with the Xplorer GLX (PS-2826). Both manuals are complete with Teacher Information pages, student instructions and handouts, and sample data.

For your convenience, we offer bundles which provide the probeware for the activities in the manual. For more, please see:
