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

The correct answer is d) Joule.<br /><br />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).<br /><br />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.<br /><br />The other options are not the correct units for work:<br /><br />a) Newton is the unit of force, not work.<br />b) ft-lb (foot-pound) is a unit of work, but it is not the standard SI unit.<br />c) Watt is the unit of power, which is the rate of doing work, not the unit of work itself.<br /><br />Therefore, the correct answer is d) Joule.
