2.2 m Classic Dynamics System Experiment 8: Acceleration Down an Incline

4. Measure the hypotenuse of the triangle formed by the track and use this to calcu-

late sin  for each angle.

Hypotenuse = __________

5. Plot acceleration versus sin . Draw the best-fit straight line and calculate its

slope. Calculate the percent difference between the slope and g = 9.8 m/s

slope = ______________________

% difference = _______________

Questions

1. Does your reaction time in operating the stopwatch cause a greater percentage

error at higher or lower track angles?

2. How will doubling the mass of the cart affect the results? Try it.
