SUMMARY

The discussion focuses on the derivation of equations for Uniform Accelerated Motion (UAM), specifically addressing the term ds/dv. The derivation presented is a concise formulation of the acceleration equation: a = dv/dt = (dv/ds)(ds/dt) = v(dv/ds). It clarifies that ds/dv is the reciprocal of dv/ds, although its fundamental significance is minimal. The conversation emphasizes the utility of this derivation in understanding motion dynamics.

PREREQUISITES
  • Understanding of Uniform Accelerated Motion (UAM)

Hello, here's a derivation for one of the equations for Uniform Accelerated Motion (UAM). I like it because it's far more concise than the algebra version. Question though: is there any kind of meaningful interpretation of ds/dv (which starts everything off in step 1)? Thank you!

The derivation is usually done as follows: $$a=\frac{dv}{dt}=\frac{dv}{ds}\frac{ds}{dt}=v\frac{dv}{ds}$$where dv/ds is the rate of change of speed with respect to distance. So ds/dv is the reciprocal of dv/ds, but it doesn't have much fundamental significance.
