Acceleration calculator

The acceleration from force and mass API applies Newton's second law of motion in its most direct form: divide the net force acting on an object by the object's mass, and you get the acceleration that force produces.

Run — free How it works & API

Use it from WebAPIEmailTelegramApp soon

You send a force in newtons and a mass in kilograms, and you receive the acceleration in metres per second squared, computed deterministically with no rounding surprises. Zero or negative mass is rejected with a clear validation error instead of a meaningless number. The same formula runs free in your browser on this page, so you can check a value by hand and only pay when you automate the call — $0.002 per request via the API.

How to use it

Enter your values in the form above. The tool checks them before calculating and shows the result on the same page.

Check your inputs

Use the labels and units shown next to each field. If something is missing or outside the allowed range, the page points to the field to fix.

Use it again or automate it

Use the browser tool for individual checks and the API when you need the same capability in an automated workflow.

What you can do with it

Get an answer now

Enter one set of values and see the result without building a spreadsheet or script.

Compare scenarios

Change one value at a time and rerun the calculation to understand what affects the result.

Automate repeated work

Use the API when the same calculation needs to run inside your product or workflow.

For developers — API access

Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.

API endpoint

POSThttps://api.kit.forhosting.com/phys/acceleration-using-force-and-mass

Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

Call it from your stack

curl -X POST https://api.kit.forhosting.com/phys/acceleration-using-force-and-mass \
  -H "Authorization: Bearer $KIT_KEY" \
  -H "Content-Type: application/json" \
  -d '{"force":20,"mass":5}'

const res = await fetch("https://api.kit.forhosting.com/phys/acceleration-using-force-and-mass", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.KIT_KEY}`,
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    "force": 20,
    "mass": 5
  })
});
const { task_id } = await res.json();

import os, requests

Example request

{
  "force": 20,
  "mass": 5
}

Example response

{
  "task_id": "tsk_a1b2c3d4e5f6a1b2c3d4e5f6",
  "type": "phys.acceleration_using_force_and_mass",
  "status": "queued",
  "_links": {
    "result": "/tasks/tsk_…/result"
  }
}

The API is asynchronous: the call returns a task_id immediately and the result arrives by webhook. Polling is capped at 1 req/s per task.

Pricing

Per request$0.002

Published price — no tokens, no invented credits. A failed task is never charged.

Errors

HTTP	Code	Meaning
`401`	`unauthorized`	Missing or invalid API key.
`402`	`insufficient_balance`	Your balance doesn't cover the task price.
`404`	`unknown_type`	That task type doesn't exist.
`429`	`rate_limited`	Too many requests. Use the webhook instead of polling.
