## Quick Answer

Calculate physical force, mass, acceleration, weight, or spring constants. Supports F=ma, F=mg, and Hooke's Law (F=kx) with full unit conversions.

## Definition

A force calculator is a physics utility that computes mechanical force using standard equations. It supports linear dynamics (F=ma), weight calculations under planetary gravity (F=mg), and spring elasticity models (F=kx), resolving for any parameter with complete unit conversion support.

## How to Use

1. **Select mode** — Choose F=ma (Newton's 2nd Law), F=mg (Weight/Gravity), or F=kx (Spring/Hooke's Law) mode.
2. **Select variables to solve** — Choose which variable you wish to calculate (e.g. Force, Mass, Acceleration, Spring Constant, or Displacement).
3. **Enter values and units** — Input the known values and specify their measurement units.
4. **Read solution** — View the calculated value converted to Newtons, pounds-force, or dynes, along with step-by-step math.
