What is the unit of force?

The unit of force is the Newton, which is defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared. This definition is rooted in Newton's second law of motion, which describes the relationship between force, mass, and acceleration. The Newton is an essential unit in the field of physics and is part of the International System of Units (SI), which standardizes measurements.

In contrast, the other options represent different physical quantities: the Watt is a unit of power, the Pascal is a unit of pressure, and the Joule is a unit of energy. Each of these units serves a specific purpose in measuring various aspects of physical phenomena, but they are not applicable for measuring force.
