** #$&* Your optional message or comment: **

** #$&* How far and through what angle did the block displace on a single trial, with rubber band tension equal to the weight of two dominoes? **

** #$&* 5 trials, distance in cm then rotation in degrees, with rubber band tension equal to the weight of two dominoes: **

** #$&* Rubber band lengths resulting in 5 cm, 10 cm and 15 cm slides: **

** #$&* 5 trials, distance in cm then rotation in degrees, with rubber band tension equal to the weight of four dominoes: **

** #$&* 5 trials, distance in cm then rotation in degrees, with rubber band tension equal to the weight of six dominoes: **

** #$&* 5 trials, distance in cm then rotation in degrees, with rubber band tension equal to the weight of eight dominoes: **

** #$&* 5 trials, distance in cm then rotation in degrees, with rubber band tension equal to the weight of ten dominoes: **

** #$&* Rubber band length, the number of dominoes supported at this length, the mean and the standard deviation of the sliding distance in cm, and the energy associated with the stretch, for each set of 5 trials: **

** #$&* Slope and vertical intercept of straight-line approximation to sliding distance vs. energy, units of slope and vertical intercept, description of the graph and closeness to line, any indication of curvature: **

** #$&* Lengths of first and second rubber band for (first-band) tensions supporting 2, 4, 6, 8 and 10 dominoes: **

** #$&* Mean sliding distance and std dev for each set of 5 trials, using 2 rubber bands in series: **

** #$&* Slope and vertical intercept of straight-line approximation to sliding distance vs. energy, units of slope and vertical intercept, description of the graph and closeness to line, any indication of curvature: **

** 1-band sliding distance and 2-band sliding distance for each tension: **

** #$&* Slope and vertical intercept of straight-line approximation to 2-band sliding distance vs. 1-band sliding distance, units of slope and vertical intercept, description of the graph and closeness to line, any indication of curvature: **

** #$&* Discussion of two hypotheses: 1. The sliding distance is directly proportional to the amount of energy required to stretch the rubber band. 2. If two rubber bands are used the sliding distance is determined by the total amount of energy required to stretch them. **

** #$&* How long did it take you to complete this experiment? **

** #$&* Optional additional comments and/or questions: **

Your responses don't seem complete. For example on the different trials you were asked for rotation as well as distance traveled. THis isn't a serious omission since the rotation isn't a big factor. However when asked for rubber band length, the number of dominoes supported at this length, the mean and the standard deviation of the sliding distance in cm, and the energy associated with the stretch you gave only two numbers for each trial, when the question asked for five. In general you didn't explain your results.

Can you copy your results into the original document for the experiment, and complete the ones that need to be completed?

I apologize for the delay in posting this assignment. The file containing my original critiques is missing. This happens very rarely and shouldn't be an issue again.
