I am studying in Grade XI and have started with physics. Its very different from physics in last grade. So here are my questions about few units my tution teacher challenged everyone about.
1. The problem statement, all variables and given/known data
i)What is the name of the unit
$$[Kg][Meter][Second]^{-3}$$ - We may write it as Force/Time.. but

ii) What is $$|Acceleration|$$

2. Relevant equations
i) By doing dimensional analysis we get $$[M][L][T]^{-3}$$ , we may also call this Force/Time. Couldn't find anything bout this unit.

ii)
$$|Vector| = Scalar$$
$$|Displacement|=Distance$$
$$|Velocity|=Speed$$
$$|Acceleration| =?$$

3. The attempt at a solution

The above is my try, couldn't do anything further.

Thanks for help.

Acceleration is the change in velocity over time

Below is a unit called yank which I googled. Its units are defined as kgms-3

Thanks mate for Yank.
I thought it will be force per unit time and change of speed per unit time.
Buit since there is a name for 1, there must be a name for the other one topo (Scalar name of acceleration), will keep searching, and hope some help frm u guys 2.
anyways, since i dont think my tutor will give something that doesnt exist, there must be a name for mod of acceleration.
