Physics 2305 Laboratory Equipment List

Lab 5: Variable Forces and Friction

Pciture of John Hughes rolling letting a cart roll down the track

This image does not really represent this lab and shouldn't be used to dictate set up.

Transition notes:

  1. Remove and put away the pulley attached to the track.
  2. Put away small pieces of string and copper.
  3. Put away the motion sensor, its cable, and the lone cart mass.
  4. Detach the force sensor from the Collision Cart and put away just the cart.
  5. Check that all tables have the correct equipment, straighten everything, tighten screws, check masses, sweepy sweepy.

Equipment List:

  1. 850 Interface with the following sensors:
    • RMS with
      yellow plug DG1, black plug DG2
    • Force Probe with hook mounted on Dyanamics Cart[Plunger Cart] (Analog A)
    • Force Probe with hook mounted on Bumper Bracket(Analog B)
  2. Acceleration Sensor
    • Mounted to the force sensor on the plunger cart using the Acceleration Sensor Screw and Acceleration Sensor Bracket such that the positive direction aligns with the force sensor's positive arrow.
    • Plugged in to the interface (Analog C) using the 8 pin Extension Cable
  3. Cart Track
    • Elevation Clamp
    • on the left side clamped to the 45cm Rod sitting in a Medium Mlamp
    • Track Angle Indecator attached with a Short Track Screw
  4. RMS Pulley System:
    • Super Pulley with the pulley downward attached to the 90 cm Rod with a Rigth Angle Clamp
    • RMS mounted to the top of the rod with the pulleys facing towards you and the 2.5m String
    • All held up by a Large UNiversal Clamp.
  5. 5N Spring Scale.
  6. 2 x 8 N/m Spring
  7. Hanging Mass Set
  8. with the following masses:
    • 1 x 10g mass
    • 2 x 20g mass
    • 2 x 50g mass
    • 1 x 100g mass
    • 2 x 200g mass
    • 1 x 500g mass
  9. 50g Mass Hanger
  10. 1 Meter Stick
  11. Electronic Balance

Notes and tests:

  1. Start “2305 Lab 5 test.cap”. Move the cart back and forth, and push and pull the force probe.   Check that they register correctly on the graph.
  2. No brass posts or cart masses needed.
  3. The RMS pulley should not be on the PASCO logo side (PASCO should be easily read).
  4. Negative on the acceleration sensor should be pointing TOWARDS the force probe hook ( the front of the cart).
  5. The bumper accessory is only to hold the force probe, the parts are not used.
  6. The end stop should be in front of the bumper accessory, the spring will go through the hole in the end stop.

This is what your table should look like once set up
