What unit is used to measure force in physics?

Force in physics is measured in Newtons, denoted as "N." This unit is named after Sir Isaac Newton, who formulated the laws of motion and universal gravitation. According to Newton's second law, force is defined as the mass of an object multiplied by its acceleration, which can be expressed in the formula F = ma. Here, mass is measured in kilograms (kg) and acceleration in meters per second squared (m/s²). Consequently, a Newton is equivalent to one kilogram meter per second squared (kg·m/s²).

The other units mentioned are related to different physical concepts: Joules measure energy, Kilograms measure mass, and Pascals measure pressure. Understanding these distinctions helps clarify why the correct answer for measuring force specifically is the Newton.
