f, what is acceleration in terms of other units?

g, All energy is measured in the same units - because energy can be converted from one to another.

Dimensional analysis is your best friend.

Formula for acceleration = change in speed / change in time

Speed is m/s. Time is s.

(m/s) / s
= m/s^2

Thus, the unit for acceleration is m/s^2.

You can apply this to nearly every unit. Some you have to know, such as newtons or pascals.
