The discussion centers on the limitations of uniformly accelerated motion equations, specifically Vf = V0 + at, D = (1/2)(V0 + Vf)t, and D = (V0)(t) + (1/2)(a)(t²). These equations are valid under constant acceleration conditions but fail over long distances due to factors like air resistance and changing acceleration. The term "long distances" lacks a precise definition, leading to confusion about the applicability of these equations in real-world scenarios.

GSaldutti said:Why don't these equations (and the rest in the set) work over long distances?
Vf= V0 + at
D= (1/2)(V0 + Vf)t
D= (V0)(t) + (1/2)(a)(t2)
etc...
