    Force Standard Unit
Click For Summary
SUMMARY

The discussion centers on creating a standard unit of force based on Newton's principles, specifically through a mechanical method involving a balance scale. The proposed method utilizes equal masses on a scale to establish a linear representation of gravitational force, with the displacement indicating force. This unit would integrate with existing concepts of speed, velocity, momentum, and energy equations, although it necessitates a standardized scale and mass for laboratory use. The need to re-derive standard mechanics equations for this new definition of force is also highlighted.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with concepts of mass and gravitational force
  • Knowledge of balance scales and their operation
  • Basic principles of mechanics and physics equations
NEXT STEPS
  • Research the principles of gravitational force and its measurement
  • Explore the design and calibration of standardized scales
  • Study the re-derivation of mechanics equations based on new force definitions
  • Investigate the relationship between force, mass, and acceleration in classical mechanics
USEFUL FOR

Physicists, mechanical engineers, educators in physics, and anyone interested in the foundational concepts of force measurement and its implications in mechanics.

Can anyone give me description of a mechanical way you would make a standard unit of force if you were Newton and on the road to creating a unit because you understood the principles behind the force unit?

I have one. When two masses are on the plates of a scale and the scale reads equal, I have two equal masses. If I change out one mass with a third piece of mass by putting it in one of the plates and the scale is still equal, I have three equal masses. When I put the mass that was taken off by putting it on the plate with the third mass, the scale is uneven. This displacement of unevenness could be used as a linear representation of the basis unit of force (gravitational force on a specific mass) for anyone of my equal masses.

Other masses weighed using the same method would have shorter or longer linear representations of force. Using a standard of distance, each length representing force would be able to be used with speed and velocity (because they would use the same standard distance unit) making it possible to use my basic unit in momentum, work, energy equations.

My unit would be based upon mass acting opon mass, through the help of gravity, and represented as a basic unit of displacement, but called force.

(Although, the curvature created by the scale of different lengths would have to be taken into account.)

If it works for you, Jolly good! I think that this would require, however, a "standardized scale" that would have to be made for each and every laboratory, as well as a standardize mass (such as the kilogram already is). So it seems that this would be a less convenient unit for research.

Now in addition, you would need to re-derive all of the standard mechanics equations. I don't see how this definition of force would work for prediciting acceleration or torque, but that's for you to work out.
 
Thanks for the response, but how would you describe the force unit for use if you were in Newtons situation? I'm interested in peoples descriptions.
