In the equation:(adsbygoogle = window.adsbygoogle || []).push({});

W_{net}=F_{net}ΔX=[m*Δv/Δt]Δx=m*Δv*Δx/Δt

I just don't understand how the 3rd part of the equation is changed into the 4rth (Dt going under the Dx). If I can get some help with this, that would be great.

The way I think about it is [m*Δv/Δt]Δx = mΔx(Δv/Δt)

I have no idea how Dt went under the Dx...
