# Definition:Particle

## Definition

A particle is a representation of an object in the physical university which is idealized as having no magnitude.

That is, it is modelled as being a mass concentrated at a single point.

## Also known as

A particle is also referred to as a point mass or mass-point if it important to emphasise the fact that it has a definite mass.

## Historical Note

The concept of a particle as a mass concentrated at a point was first explicitly introduced by Leonhard Paul Euler in $1736$.
