## Definition

A **particle** is a representation of an object in the physical universe 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 $1736$.
