Final answer:
The Pascal is not a correct unit for work; it is a unit of pressure. Work is measured in joules, which is the product of force (in newtons) and distance (in meters).
Step-by-step explanation:
The unit that is not a correct unit for work is the Pascal (Pa). Work is defined as the product of force and distance, which is given in the units of newton-meters (N∙m), equivalent to joules (J). One joule is the amount of work done when a force of one newton is applied over a distance of one meter. Watts (W) is a unit of power, which is the rate at which work is done, and is defined as one joule per second (1 W = 1 J/s). In contrast, a Pascal is a unit of pressure, defined as one newton per square meter (1 Pa = 1 N/m²), and is not a measure of work.
