SUVAT: The five constant-acceleration equations — give any three, get the rest. This free calculator solves for Any 2 of s, u, v, a, t and shows every step.
The five SUVAT equations connect the five kinematic variables for any motion at constant acceleration. Each equation omits one variable, so once you know any three you can find the remaining two.
Start from rest (u = 0), a = 2 m/s², t = 5 s. v = 0 + 2·5 = 10 m/s; s = 0 + ½·2·5² = 25 m.
Vehicle braking and acceleration distances, train and runway calculations, and exam problems — any straight-line motion with steady acceleration.
SUVAT uses the formula v = u + at · s = ut + ½at² · v² = u² + 2as. The five constant-acceleration equations — give any three, get the rest.
Choose which variable to solve for, enter the values you know (in any supported unit), and the calculator substitutes them into v = u + at · s = ut + ½at² · v² = u² + 2as and shows every step of the working. It can solve for Any 2 of s, u, v, a, t.
