WebAug 24, 2024 · First, measure the final velocity of the object. Next, determine the total time that has passed. Next, determine the acceleration acting on the object during that time period. Finally, plug those three values into the formula above to get initial velocity. For example, given V2=5, a = 2, t =2, solving: V1 = 5-2*2 = 5-1 = 1. FAQ WebSep 12, 2024 · Displacement Δ x is the change in position of an object: (3.2.1) Δ x = x f − x 0, where Δ x is displacement, x f is the final position, and x 0 is the initial position. We use the uppercase Greek letter delta ( Δ) to mean “change in” whatever quantity follows it; thus, Δ x means change in position (final position less initial position).
