What is the unit used for work? a Newton ft-lb Watt o Joule

The correct answer is d) Joule.Work is a measure of the energy transferred to or from an object when a force is applied to it. The unit used for work is the Joule (J), which is the standard unit of energy in the International System of Units (SI).The Joule is defined as the amount of work done when a force of one newton is applied over a distance of one meter. It is also the unit of energy, which is the ability to do work.The other options are not the correct units for work:a) Newton is the unit of force, not work.b) ft-lb (foot-pound) is a unit of work, but it is not the standard SI unit.c) Watt is the unit of power, which is the rate of doing work, not the unit of work itself.Therefore, the correct answer is d) Joule.
