The experiment output an average efficiency of 80.5% +- 5.25%.
Conclusion
The cart had a higher velocity going down the incline and the magnets ensured it did not hit the bumper and returned the cart up the incline with a smaller velocity. The total efficiency that the cart going up and down the ramp was 80.5% +- 5.25%.
The efficiency from group three on a leveled track was calculated to be 90.285% +- 5.09%. The velocity changed only 10% on average after the cart hit the bumper. This shows that the incline has a large effect on the carts total motion and the flat surface helps retain the motion.
The leveled track would be a better way to measure since it is easier to gather data and less factors like angles and friction becoming more of a problem. The inclined track was also harder to measure the heights and positions since we have to use trigonometry to calculate.
