Definition

A 'newton' is the standard unit of force in the International System of Units (SI), defined as the force needed to accelerate a 1 kg mass by 1 meter per second squared. It is also used as a surname, most famously by physicist Isaac Newton.

Usage & Nuances

In science, 'newton' always refers to the unit of force, symbolized as N. It is a formal, technical term, not used in everyday conversation. As a surname, it’s capitalized: 'Sir Isaac Newton'. Never use 'newton' for weight or mass—it is specifically a unit of force.
