Finding the mass of a object without a scale or density

Click For Summary

Homework Help Overview

The original poster is tasked with determining the mass of two objects using lab equipment and 50g mass pieces, without the use of a scale or knowledge of density. The context involves exploring the concept of mass in relation to fundamental units.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the idea that mass may not be a fundamental unit and can be expressed in terms of length and time. There is mention of using a standard mass as a basis for comparison, but specific methods or calculations are not detailed.

Discussion Status

The discussion is ongoing, with participants sharing thoughts and exploring different perspectives on the nature of mass. Some express uncertainty about how to proceed, while others suggest reconsidering the fundamental concepts involved.

Contextual Notes

There is a noted constraint of not being able to use a scale or density in the problem-solving process, which may limit the approaches available to the participants.

do you at least have some entertaining thoughts or shots-in-the-dark?

I have somewhat a of a purist physics professor, who (out of the class room) argues that mass isn't really a fundamental unit... only length and time are, and other so-called 'fundamental units' like mass can be expressed in terms of length and time. (Hint: in the case of mass, you won't need time)

You're lucky enough to have a standard (a 50 g wait) to be your basis ratio of lengths.
 
The only tring I could think of was Newtons 3 Laws , because that is what we are busy with in class
 
I think I would table this whole project rather than force an answer?
:rolleyes:
