Acceleration Calculator

Enter initial velocity, final velocity, and time to calculate average acceleration in m/s² and ft/s².

Initial velocity

Final velocity

Elapsed time (s)

—m/s²

—ft/s²

—standard g

—Δv m/s

—Average acceleration = (vf − vi) / Δt

These are idealized classical-physics calculations. Real systems can differ because of air resistance, friction, deformation, measurement uncertainty, non-constant forces, or other effects not included in the selected model.

How to use this Acceleration Calculator
