What Units Should Acceleration Be Measured In?

Click For Summary

Homework Help Overview

The discussion revolves around the appropriate units for measuring acceleration, specifically whether it should be expressed in m/min² or the standard SI units of m/s². Participants are examining the implications of using different units in the context of a graph where the x-axis represents time in minutes and the y-axis represents distance in meters per minute.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the validity of using m/min² for acceleration and whether it is acceptable compared to the standard m/s². There is also a discussion about the importance of unit consistency and conversion between different time units.

Discussion Status

Some participants have provided guidance on the acceptability of using non-standard units, while others emphasize the importance of adhering to SI units. The conversation reflects a mix of perspectives on unit conversion and standardization without reaching a definitive consensus.

Contextual Notes

The original poster is working with a given graph for an assignment, which may limit the ability to change the time units from minutes to seconds. There is an acknowledgment that the question is straightforward, yet the original poster feels uncertain about the correctness of their answer.

the x-axis is in minutes, the y-axis is in m/min.

I know that the acceleration = the slope.

should my final answer be in m/min^2 ?

or should acceleration always be in m/s^2 ?

or does it not matter? :confused:


thanks :smile:

There is nothing wrong with m/min^2 aside from it not being standard. Your best bet is just graphing it against seconds by converting your data from minutes to seconds BEFORE graphing.
 
yeah if I was taking down the data I would.
This is just a question on an assignment, where the graph is given.

Its an easy question, but after I did it the answer just doesn't look right to me, so I figured I'd ask.

acceleration has been in m/s^2 everytime I have come across it.
 
That is because meters and seconds are the SI units for time and distance. It is the international standard.
 
As whozum said, no problem at all. The important thing is that the units are distance over time squared. Remember that you can always convert between the standard m/s^2 and the non-standard m/min^2.
