Working

  1. 1a = (27.8 − 0) ÷ 6.2 = 4.4839 m/s²

Quick answer

Acceleration is the change in velocity divided by the time taken.

a = (v − u) ÷ t

Frequently asked questions

What is a fast 0–60?

Under 5 seconds is quick, under 3 is supercar territory — about 0.9 g of sustained acceleration.

Is deceleration negative acceleration?

Yes, mathematically it's the same quantity with the opposite sign.

What do I need to enter into the Acceleration Calculator?

Just 3 values: initial velocity, final velocity, time taken. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.

How does the Acceleration Calculator work out the answer?

Acceleration is the change in velocity divided by the time taken. It applies the formula a = (v − u) ÷ t and shows the working so you can check each step by hand.

Is the Acceleration Calculator free, and do I need an account?

It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
