When measuring work done in a mechanical context, which unit is typically used?

The unit typically used to measure work done in a mechanical context is Joules. Work is defined as the energy transferred when a force is applied over a distance. In the International System of Units (SI), one Joule is defined as the amount of work done when a force of one Newton is applied over a displacement of one meter. This close relationship between force, distance, and energy transfer is fundamental in physics, making Joules the appropriate unit for quantifying work.

In contrast, Newtons refer to the unit of force, which is not specific to work output alone. Pascals measure pressure, which relates to force per unit area and is not directly applicable to measuring work. Watts quantify power, representing the rate at which work is done or energy is transferred over time, rather than the total work itself. Thus, Joules is the clear and correct choice for measuring work in a mechanical context.
