Question

Which equation is most likely used to determine the acceleration from a velocity vs. time graph?

a = t over delta v.
m = StartFraction v subscript 1 - v subscript 2 Over x subscript 2 minus x subscript 1 EndFraction.
a =
m = StartFraction x subscript 2 minus x subscript 1 Over v subscript 1 - v subscript 2 EndFraction.

Answer 1

Acceleration from a velocity vs. time graph is the slope, so

a = Δv / Δt = (v₂ − v₁) / (t₂ − t₁).

Units: m/s². The other choices are either inverted (t/Δv) or use position x instead of time.
