## Introduction

Kinetic energy is the energy an object possesses due to its motion, while torque is the rotational force applied to an object. Understanding the relationship between kinetic energy and torque is crucial in designing and analyzing mechanical systems, such as engines, gears, and flywheels.

## Formula:

The formula for calculating torque ($T$) from kinetic energy ($KE$) is based on the relationship between angular velocity ($ω$) and linear velocity ($v$):

**$T=r⋅KE $**

Where:

- $T$ represents the torque (in newton-meters or foot-pounds).
- $KE$ is the kinetic energy (in joules or foot-pounds) of the rotating object.
- $r$ is the radius (in meters or feet) at which the torque is measured.

## How to Use?

Using the Kinetic Energy to Torque Calculator involves these steps:

**Determine Kinetic Energy (KE)**: Find the kinetic energy of the rotating object. Ensure you use consistent units (joules or foot-pounds).**Determine Radius (r)**: Measure or determine the radius at which you want to calculate the torque. Make sure to use consistent units (meters or feet).**Plug Values into the Formula**: Input the kinetic energy (KE) and radius (r) into the formula.**Calculate Torque (T)**: Use the calculator or perform manual calculations to determine the torque.

## Example:

Let’s illustrate the calculation with a practical example:

Suppose a flywheel with a kinetic energy of 1,000 joules is rotating with a radius of 0.5 meters. Calculate the torque generated by the flywheel.

Using the formula:

**$T=m⋅,joules =4,000newton-meters (N\cdotpm)$**

So, the torque generated by the flywheel is 4,000 N·m.
