To study the relationship between work, potential energy, and kinetic energy




  1. Connect the motion probe to the sonic port on the CBL. Turn on the Vernier PHYSICS program in your TI-83.
  2. Set the probes for one motion probe
  3. Collect data using the time graph option and the live display option.
  4. Enter time between samples as 0.01 and number of samples as 80.
  5. Set the graph options on the program as ymin=0, ymax=1, yscl=0.1.


Calculate the following values making sure to include formulas with units for all calculations. Make sure your answers reflect the correct number of significant figures.

  1. Change in time
  2. Distance traveled
  3. Average velocity
  4. Final velocity (assume constant acceleration)
  5. Potential energy at the top of the run (use length of run and Q )
  6. Kinetic energy at the end of the run
  7. Work done by gravity
  8. Percent difference between potential energy at the top and the kinetic energy at the end of the run
