A formula for calculating the acceleration measured by physical dot timer in grade one of senior high school I remember it was a delta x = at ^ 2 Is it this one?

Yes, there is one
Δ x is the length difference between two adjacent strips, a is the acceleration of the object, and T ^ 2 is the square of the time passing through each strip
There are other formulas
For example, s3-s1 = a * 2T ^ 2. Where S3 and S1 refer to the third tape and the first tape, and the 2 in the following 2T ^ 2 is determined by the number difference in the lower right corner of two S
Another calculated acceleration is the most accurate. A = [(S6 + S5 + S4) - (S3 + S2 + S1)] / 9t ^ 2
Because I'm also a freshman in high school, so I have some impression
