The formula of measuring acceleration with dot timer What is the general formula of acceleration measured by dot timer? The acceleration of N segments is required! For example, when n = 6, there are six segments S1, S2, S3, S4, S5, S6!

N must be even. A = [Sn + s (n-1) + s (n-2) + -S(n/2)-S(n/2-1)-s1]/(n/2)^2*T^2
