Frequently Asked Questions
How is acceleration calculated?
Acceleration is the change in velocity divided by the time taken: a = (v − v₀) / t. Units are m/s².
What units does this calculator use?
SI units throughout: m/s for velocity, s for time, m/s² for acceleration, m for displacement.
Can it solve for displacement?
Yes - whenever you solve for any of the four variables, displacement under constant acceleration (x = v₀t + ½at²) is reported as a secondary output.
How do I convert mph or km/h to m/s first?
This calculator expects m/s, so convert your speeds before entering them. Divide km/h by 3.6 (1 km/h = 0.278 m/s), or multiply mph by 0.447 (1 mph = 0.447 m/s). Example: a car going 0 to 60 mph is 0 to 26.8 m/s; if it takes 6 s, acceleration = 26.8 / 6 ≈ 4.47 m/s². Convert both the initial and final speeds so the result comes out in m/s².
