Discussion Overview

The discussion revolves around the conversion of miles per hour (mph) to pound-force (lb-force). Participants explore the relationship between speed and force, questioning the validity of such a conversion and the context in which it might be necessary.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant suggests that to find force when decelerating from a given mph to zero, one could use the formula F = MA, where mass is in pounds.
  • Another participant expresses confusion regarding the original question and the provided answer, seeking clarification on the context of converting speed to force.
  • A different participant asserts that mph and lb-force are units of entirely different quantities, comparing the conversion to asking how to convert feet to hours.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the possibility of converting mph to lb-force, with some arguing against the conversion and others attempting to relate the two through force calculations.

Contextual Notes

The discussion lacks clarity on the specific context or application for converting speed to force, which may influence the understanding of the problem.

How would I convert mph into lb-force?

Thank you.

If it's decelerating from the given mph to zero, multiply by the mass in pounds: F = MA

hmm … i don't understand either the question or the answer :confused: …

what is the context? why exactly are you trying to convert a speed into a force?
 
You don't convert between these two. These are units of completely different quantities. It's like asking how to convert between feet and hours. You can't.
