Unformatted text preview: values are higher then the calculated values, as I would think friction would slow acceleration down. As I think about it, if friction slowed the cart more for V1 then for V2 you would end up with higher acceleration values. That is, if overcoming static friction slowed the carts start and effected our V1 times, we would end up with artificially high values for our acceleration. Another idea is that the effects of friction would show up more in V1 because T1 is a larger value, so it really wouldn’t be an instantaneous velocity. By the time the carts velocity was measured it was much higher. Perhaps friction would effect T2 less as the time interval was so much shorter. These are some of my ideas, but bottom line I find a large difference in a exp and a calc . I would have to blame either the effects of friction or experimental error....
