What is the unit of force?

Explanation:
Force is measured in the newton. A single newton is the force that gives a mass of 1 kilogram an acceleration of 1 meter per second squared, or in base units, 1 N = 1 kg·m/s^2. This comes directly from Newton’s second law, F = ma. The other units point to related but different quantities: a unit like newton per square meter is a pressure unit (pascal), and the joule is a unit of energy (work). So while those are connected to forces and motion, they describe pressure and energy, not force itself.
