You may use the average speed for each track shape to make a single work calculation since | already told all of you to calculate the average speed for each track. e Calculate the percent error for the three non-straight tracks. Conclusion: Answer the question \"does the work of friction depend on the shape of the track?\" If the work is different, explain whether this means the force of friction must be different or the same for each track and explain what causes this to be the case. If the work done by friction is the same, explain why this is the case using the concepts of conservation of energy as your main reasons. Let a percent error of less than 10% mean that the velocities are within experimental uncertainty. Any percent error that is greater than 10% means that experimental error is not enough to account for these differences. Percent errors should be measured against the \"straight\" track, taking that as the expected value
