Question

What is the SI unit of work is the newton?

Answer 1

Hint: We need to know that the new version of the metric system is the International System of Units (SI). It is the only method of measuring recognised by almost every nation on the planet. It is made up of a logical system of measuring units that starts with seven basic units. The SI, like all metric systems, employs metric prefixes to provide a collection of units that are decimal multiples of each other over a wide spectrum with the same physical quantity.

Complete answer:
We also remember that the work is the energy that is transmitted to or from an object as stress is applied along a displacement. It is often represented as the product of force and displacement in its simplest form. As applied, a force is said to do positive work if it has a part in the direction of the point of application's displacement. If a force has a part that is opposite the direction of displacement at the point of application, it does negative work. Work is a scalar quantity, which means it only has a magnitude and no direction. Work is the process of transferring energy from one location to another or from one medium to another. The joule (J), which is the same unit as electricity, is the SI unit of work.
Hence, the SI unit of work is Joules (J).

Note:
We need to remember that the joule (J), named after ${19^{th}}$-century English physicist James Prescott Joule, is the SI unit of work. It is defined as the work needed to exert a force of one newton through a displacement of one metre. The dimensionally equivalent newton-metre (Nm) is often used as a unit of work measurement, but this should not be confused with the torque measurement unit. The SI authority discourages the use of Nm because it can cause doubt as to whether a quantity expressed in newton metres is a torque measurement or a work measurement.
