In this Lab Practical, students determine the mass of an object on an incline using a Force Sensor.

• Microsoft Word version of this lab:
  
  • forcePracticalGLX_docs.zip (3.3 MB)

• Xplorer GLX (PS-2002)
• Force Sensor (PS-2104)
• Accessory Bracket with Bumpers (CI-6545)
• Optional: Angle Indicator (ME-9495)
• Large Base and Rod (ME-9355)
• Track from the PAScar Dynamics System (ME-6955)
• Ohaus Triple-Beam Balance (SE-8723)

1. The teacher will set up the lab practical as in the picture above.
2. When the teacher has given permission, press the button on the GLX.
3. Record any data you think is necessary to determine the mass of the object on the incline.

• Show all work related to your determination of the mass of the object on the incline.

1. Draw a labeled, qualitative force (free-body) diagram of the object.
2. Redraw the force diagram. Include the horizontal and vertical components of each force.
3. Write an equation that relates the horizontal forces.
4. Write an equation that relates the vertical forces.

1. Repeat the experiment with a different angle on the incline.
2. Relate and explain the differences (if any) between the masses calculated from each set up.
