A newton meter is a measure of work and is also known as the joule (J).
To understand why a newton meter is another name for the joule, we need to understand the concepts behind work and energy.
Work is defined as the product of force and displacement. In physics, work is done when a force acts on an object to cause it to move in the direction of the force. The unit of force in the International System of Units (SI) is the newton (N), named after Sir Isaac Newton.
On the other hand, energy is the capacity to do work. It exists in various forms such as kinetic energy (energy of motion), potential energy (energy of position), thermal energy, etc.
The joule is the SI unit of energy, named after James Prescott Joule. It is also equivalent to the amount of work done when a force of one newton acts over a distance of one meter. Mathematically, 1 joule (1 J) is equal to 1 newton meter (1 N·m).
So, when we refer to a newton meter, we are essentially referring to the amount of work done, which is also measured in joules.
