The methods used to measure automobile acceleration in physical experiments can sometimes be used to solve some sports problems.

The formula is δ s = at 2.

For objects with uniform change, the difference of moving distance in adjacent equal time periods is the same.

For example, the moving distance of a car x 1 is 0~5s, x2 is 5 5~ 10/0s, and x3 is10s/5s. ......

δS = x2-x 1 = x3-x2 ......
