If there is an object moving in a straight line with uniform acceleration and zero initial velocity, and the acceleration is 3m / S ^ 2, then: What is the difference between the displacements of two adjacent ones within 1 s? How to calculate the displacement ratio in the first second, the second and the third seconds? How to calculate the ratio of the average speed in the first second, the second and the third seconds? How to calculate the ratio of initial velocity at the end of 1s, 2S and 3S?

The displacement difference between two adjacent 1s is at2 = 3 * 1 = 3M, the displacement ratio S1: S2: S3 = 1 / 2A * 1 ^ 2:1 / 2A (2 ^ 2-1 ^ 2): 1 / 2A (3 ^ 2-2 ^ 2) = 1:3:5, the average velocity ratio V1: v2v3 = S1: S2: S3 = 1:3:51s, 2S and 3S
