Question

What does M/`s^2` measure?

Answer 1

Acceleration.

Explanation:

I assume you mean `m/s^2`...

That is the measurement of acceleration. It is derived from the distance divided by the time - squared (also read as "per second per second).

This is because acceleration does not measure velocity. Instead, it measures the changes of speed in a time interval, typically in seconds.

The acceleration can be calculated by this formula: `a=(Deltav)/(Deltat)`. Where...
=> `a` is the the rate of change of the velocity (AKA acceleration) in the derived units.
=> `Deltav` is the change in speed in its respected units.
=> `Deltat` is the change in time in the time alloted, normally seconds.

I won't go too far into acceleration because that's not what you're asking, but I hope the information I provided answers your question!

Hope this helps :)
