# 1st Equation of Motion for Rotation - Angular Velocity

## Description

In mathematical physics, equations of motion are equations that describe the behaviour of a physical system in terms of its motion as a function of time.This equation applies to a particle moving linearly, in three dimensions in a straight line, with constant acceleration.Since the vectors are collinear (parallel, and lie on the same line) – only the magnitudes of the vectors are necessary and because the motion is along a straight line, the problem effectively reduces from three dimensions to one.
