# Calculator of angular motion. Power, torque and angular velocity

## Introduction

The equation that relates these thress parameters is:

** **
where:

*
P: Power (W) *

T: Torque (N·m)

ω: Angular velocity (rad/s)

If speed is in revolutions per minute (rpm), the equations is as follows:

where N is speed in rpm.

## Definitions

### Speed:

Rotational speed of the object rotating around its axis. Is the number of turns in one minute (revolutions per minute or r.p.m)

### Torque:

Torque is the rotational version of a force. It is a measure of the force that can cause an object to rotate about an axis.

### Power:

Product of a torque on a shaft and the shaft's rotational speed.
