Question

Why does the unit of time come twice in the unit of acceleration (2marks)
(please answer it elaborately)​

Answer 1

Answer:

Following is the answer.

Explanation:

We know that the unit of velocity is m/s.

Acceleration is the Rate of Change of Velocity.

It means velocity is changed by how much in what time.

Therefore:-

a= Change in Velocity/Total time

If we calculate their units, we get:-

a(unit) = (m/s)/s

          = m/s^2

I hope you get it.
