Clock tape What's special about this t? (I mean, for example, how many squares of 0.02 seconds are used for x4-x3 and x4-x1, respectively)?

Clock tape What's special about this t? (I mean, for example, how many squares of 0.02 seconds are used for x4-x3 and x4-x1, respectively)?

The paper tape of the timer is generally T = 5 * 0.02 = 0.1 seconds,
The acceleration is calculated with x = at ^ 2,
For example: x4-x3 = a [(4-3) t] ^ 2
For example: x4-x1 = a [(4-1) t] ^ 2
The actual is the difference between the square marks of X
