Unformatted text preview: decrease too much because we were deceleration too much. We can use the relationship between distance, velocity and time to calculate the result from the raw data. We know that the average velocity is calculated by the whole distance divided by the time and the instantaneous velocity is at the certain time the ratio of change in distance divided by the change in time. The experimental error only effect a little bit on our results because we use the really small amount of number, but if we use large quantity of number, it will result a big different in the effect. However, due to the fact we have to round number during the calculation process, we still have some errors between the result and experiment....
