Acceleration Calculator

    Find acceleration from velocity and time, force and mass, or circular motion radius and speed.

    Linear mode shows average acceleration over the selected interval. G-force is the ratio to standard gravity.
    Average acceleration

    about 0.0833 km
    Interpretation
    Over 6 s, velocity changed from 0 to 27.78 m/s. The sign follows your chosen direction: a negative value means braking or acceleration in the opposite direction.

    Acceleration from velocity and time

    Acceleration calculator intent is broader than one formula: users often need velocity change over time, Newton's second law, or centripetal acceleration for circular motion.

    a is average acceleration, v_f final velocity, v_i initial velocity and t elapsed time.

    F is force, m is mass and a is acceleration.

    G-force and signs

    The linear mode preserves the sign of acceleration based on your chosen direction. G-force is shown as a magnitude relative to standard gravity.
