WebDisplacement Δ x is the change in position of an object: Δ x = x f − x 0, 3.1. 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). Web28 de dez. de 2024 · Motion graphs, also known as kinematic curves, are a common way to diagram motion in physics. The three motion graphs a high school physics student needs to know are: Position vs. time ( x vs. t ) Velocity vs. time ( v vs. t ) Acceleration vs. time ( a vs. t ) Each of these graphs helps to tell the story of the motion of an object.
