Why is the SI unit of acceleration meters per second squared?

Question

science homework, need i say more.

Answer 1

Acceleration is the variation of speed over a period of time.

Let's say you go from zero to 10m/s over a 5 seconds period. Your acceleration would be calculated with (10-0)/5.

That answer would be 2 m/s per second, or 2 m/s.s or 2 m/s²

Answer 2

Because the SI Unit for distance is the meter (or metre) and the SI Unit for time is the second.

Naturally, using these two SI Units, we can form m/s^2

Answer 3

Because the Acceleration is the variation of a speed per time unit. We could easily say that it represents how much the speed increases every second.
So, because the Speed, in the SI, is given by [m/s], the Acceleration must be given by [[Speed]/s] = [(m/s)/s] = [m/(s*s)]
