Homework Help: Brief formula algebra question

  1. Apr 20, 2013 #1
    Hi all. Am I correct in that dt = Δt?

    1. The problem statement, all variables and given/known data
    Show that F = [itex]\frac{Δp}{Δt}[/itex] is equal to F = ma

    2. Relevant equations
    a = [itex]\frac{Δv}{Δt}[/itex]
    p = mΔv

    3. The attempt at a solution
    F = [itex]\frac{Δp}{Δt}[/itex]
    F = [itex]\frac{mΔv}{Δt}[/itex]
    F = ma

    Δ usually means a finite difference. You can replace Δ with d in the limit where the difference goes to 0. In this case, I think they probably should have used d to begin with. So yes, I think that should be ok.

    My apologies, they did use d to begin with. I typed it incorrectly.
