Our Conclusion

What we found out from this experiment might not be true. We could have miscalculated when the sneaker started to move, and our theory is probably not consistent. For example, a possible source of error was the semi-running shoe's starting frictions. It was much higher than the other's. From this experiment we learned that the semi-running and walking shoe has the greatest friction. We found out that the running shoe's friction was much less than the other's too, so the data could have been correct or miscalculated. Also, we learned that the shoe's friction varies according to the type of tread pattern.
