Newton's Second Law of Motion





  1. Attach a string to a cart and pass the string over a smart pulley, which is clamped to the edge of a lab table.
  2. Attach the TI-82 and CBL to the smart pulley.
  3. Load masses on your cart and on the string hanging from the smart pulley so that
  4. the total load is always 200 grams.
  5. Turn on the calculator and the CBL and use the program, "Photogate Timing with the CBL."
  6. Allow the mass on the string to fall and pull the cart across the table while the calculator accumulates the times and position readings.
  7. Perform at least five trials, each with a different mass on the hanging string.
