What is the SI unit of force?

The SI unit of force is the Newton, which is denoted as "N." A Newton is defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared. This relationship is rooted in Newton's second law of motion, which states that force equals mass times acceleration (F = ma).

The unit is named after Sir Isaac Newton, who made significant contributions to our understanding of motion and force. In practical terms, using the Newton as the unit of force allows scientists and engineers to quantify how much push or pull is exerted in various situations, making it essential for calculations in physics, engineering, and many other fields that deal with forces.

In contrast, a pound is a unit of force commonly used in the imperial system, the joule is a unit of energy, and the volt is a unit of electric potential. Each of these units serves different purposes and is not used to measure force in the International System of Units (SI).
