What is the SI unit of force?
Answer
Newton
The Newton (N) is the SI base unit of force, named after Sir Isaac Newton to honor his laws of motion. One Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared (1 N = 1 kg·m/s²). The Newton is fundamental to physics and engineering, used in calculations involving dynamics, mechanics, and forces. Other units like dynes (CGS system) and pounds-force (imperial system) also measure force but are not part of the SI standard.
💡 Did you know?
One Newton is roughly the gravitational force on a small apple (about 100 grams) at Earth's surface.
