X(s) is now called the reference input. The purpose of the negative feedback loop is to make the system output equal to the system input, by identifying large differences between X(s) and Y(s) and correcting for them.
What unit of measurement is used for acceleration? In SI, acceleration is measured in meters / second2, or meters / second / second. In other units, units of the same dimension have to be used, i.e., [length] / [time] / [time] â¦ .For example, in the imperial units, feet per square second is quite common.1 person found this useful.

If you travel to other countries, you will see that road signs list distances in kilometers and milk is sold in liters. People in many countries use words like âkilometer,â âliter,â and âmilligramâ to measure the length, volume, and weight of different objects. These measurement units are part of the metric system. Unlike the U.S. customary system of measurement, the metric system is based on 10s.
