What are the units of force in the metric system?

The metric unit of force is the Newton. This unit is named after Sir Isaac Newton in recognition of his contribution to the understanding of the laws of motion and universal gravitation. A Newton is defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared. Understanding this relationship highlights how mass and acceleration relate to force, which is fundamental to the laws of physics.

The other choices represent different physical quantities measured in the metric system. Pascals measure pressure, Joules measure energy, and Volts measure electric potential. Each of these units pertains to different aspects of physics, but when discussing force specifically, the correct unit is the Newton.
