Which unit of force is equivalent to Newton (N)?

The unit of force equivalent to a Newton (N) is defined within the context of physics as the force required to accelerate a one-kilogram mass by one meter per second squared. While Joule (J) is a unit of energy, it can be connected to Newton in terms of work done — where one Joule is equivalent to one Newton of force applied over one meter. This relationship emphasizes that the two units are related but represent different physical quantities.

In contrast, Pascal (Pa) is a unit of pressure and is defined as one Newton per square meter, further differentiating it from force itself. The decibel (dB) is a logarithmic unit used to express sound intensity or power ratios, and coulomb (C) is the unit of electric charge. Each of these other units represents separate concepts in physics, reinforcing that Joule is the most closely related unit in the context of force and work.
