Constant-Acceleration Equations

v = u + at   s = ut + ½at²   s = (u + v) ÷ 2 × t   v² = u² + 2as

u is initial velocity, v final velocity, a acceleration, t time and s displacement. Negative acceleration means slowing down (in the direction of motion).

Worked Example

Tips

These only hold when acceleration is constant. Free fall near Earth’s surface is a = 9.80665 m/s² downward (ignoring air resistance).
