Start at Vi =
or tap the line at t = 0 s
The road · where the object is and how fast it moves
Reading the graph: above the t-axis = moving forward · below = moving backward · on the t-axis = at rest · flat line = constant velocity · steeper line = bigger acceleration · shaded area = Δx.
Leg by leg
Build your trip, then press Finish trip to see Vi, Vf, a, Δx and d for each leg.
a = (Vf − Vi) ÷ Δt · Δx = area under the line (above the t-axis +, below −) · d = the same areas, all counted +
