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

Transition notes:

  1. Put away small pieces of string and copper.
  2. 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:
  2. Smart Cart - Red
    • With 2x Brass Posts and 2x Cart mass - 500g
    • And Magnetic Cart Bumper attached to the front
  3. Smart Cart - Blue
    • With Force Probe Hook attached to the front
  4. Cart Track
    • Elevation Clamp
    • on the right side clamped to the 45cm Rod sitting in a Medium Clamp

  5. Track Pulley (Pasco) attached to the end of the track that is secured with the rod
  6. 2 x 8 N/m Spring
  7. String - 1.75 m
  8. Hanging Mass Set
  9. 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
  10. 50g Mass Hanger
  11. 1 Meter Stick
  12. 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 hook.   Check that they register correctly on the graph.
  2. The track bumpers should be placed at least 1 m apart and the one on the right hand side should be positioned such that the mass hanger just touches the floor when the smart cart rests against it
