Tool 513 · Motion & trajectory solver
Kinematics Calculator
Solve any three-variable SUVAT problem, preserve multiple physical roots, model vertical free fall and 2D projectile motion, or generate a motion table — with unit conversion, sign coaching and local graphs.
Any 3 of 5s, u, v, a, t → solve the other two.
Root-awareDoes not silently discard a second valid time/velocity branch.
2D projectileUnequal launch/landing heights supported.
Motion tablesGenerate s(t) and v(t), export CSV, inspect reversals.
Enter exactly three known SUVAT values
Signs matter. Pick a positive direction and keep it consistent; the solver works in SI internally.
Known values — leave exactly two blank
Constant acceleration, straight-line motion. Negative values are allowed for s, u, v and a. Physical time is constrained to t ≥ 0.
Ideal projectile — no air resistance
Vertical motion — upward is positive
Ground is y = 0. Positive initial velocity means upward. Air resistance is ignored.
