The unit of force is the Newton, which is defined in the International System of Units (SI). One Newton is the amount of force required to give a mass of one kilogram an acceleration of one meter per second squared. This relationship is articulated in Newton's second law of motion, demonstrating the intrinsic link between mass, acceleration, and force.

The other options represent different physical quantities: a Joule measures energy or work, a Pascal measures pressure (defined as one Newton per square meter), and a Watt measures power (the rate of doing work or transferring energy). Each of these units is essential in their respective contexts but does not relate to the concept of force as directly as the Newton does. Thus, the correct response for the unit of force is indeed the Newton.
