Motion Graph Builder: v–t

Grade 12 · Physics · Velocity–time graphs

Choose the starting velocity Vi, then move the dot to build a trip on the v–t graph. Each square is 1 m/s up and 1 s across. The object starts at x = 0 m. Press Finish trip to see Vi, Vf, a, Δx and d for each leg.

Start at Vi = 0 m/s 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

a = (Vf − Vi) ÷ Δt · Δx = area under the line (above the t-axis +, below −) · d = the same areas, all counted +
