Acceleration describes the rate at which velocity changes over time. Using the fundamental kinematic equation a = Δv ÷ t, you can solve for acceleration, initial velocity, final velocity, or elapsed time from any two known values.
Linear acceleration a equals the change in velocity (final minus initial) divided by elapsed time: a = (v − u) / t. Rearranging gives v = u + at, u = v − at, and t = (v − u) / a.
The calculator also computes distance travelled using s = ut + ½at², and expresses acceleration in multiples of g (9.80665 m/s²), which is useful for understanding physiological effects such as in aviation or motorsport.
Consumer cars typically accelerate at 3–7 m/s² (0.3–0.7 g). Formula 1 cars can reach 15 m/s² (~1.5 g) under acceleration and over 50 m/s² (5 g) during emergency braking. Fighter pilots experience 7–9 g in sustained turns.
Common unit conversions: 1 g = 9.80665 m/s²; 1 km/h/s = 0.278 m/s²; 1 ft/s² = 0.305 m/s².
Frequently asked questions
Velocity is the rate of change of position (how fast you are moving). Acceleration is the rate of change of velocity (how fast your speed is changing). You can be moving fast at constant speed (zero acceleration) or moving slowly while accelerating rapidly.
Force equals mass times acceleration (F = ma). This calculator handles kinematics — motion relationships — without mass. To find force, multiply the calculated acceleration by the object's mass.
