SUMMARY

The discussion confirms that the equation F = Δp/Δt is equivalent to F = ma, where F represents force, Δp is the change in momentum, and Δt is the change in time. The relationship is established through the definitions of acceleration (a = Δv/Δt) and momentum (p = mΔv). The user clarifies that Δ typically denotes a finite difference, while d represents an infinitesimal change, suggesting that the notation should be consistent for clarity.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion

Hi all. Am I correct in that dt = Δt?
Thankyou!

Homework Statement


Show that F = \frac{Δp}{Δt} is equal to F = ma

Homework Equations


a = \frac{Δv}{Δt}
p = mΔv

The Attempt at a Solution


F = \frac{Δp}{Δt}
F = \frac{mΔv}{Δt}
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.
