The unit of force in the metric system (SI system) is the newton , symbolized as N. One newton is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. In SI base units, this is expressed as:
1 N=1 kg⋅m/s21\text{ N}=1\text{ kg}\cdot \text{m/s}^21 N=1 kg⋅m/s2
This means that a force of one newton will cause a 1 kg mass to accelerate at 1 m/s²
. The newton is named after Sir Isaac Newton in recognition of his work on classical mechanics, particularly his second law of motion, which relates force, mass, and acceleration. In summary:
- Unit: newton (N)
- Definition: Force to accelerate 1 kg at 1 m/s²
- SI base units: kg⋅m/s2\text{kg}\cdot \text{m/s}^2kg⋅m/s2
This is the standard and internationally accepted unit of force in the metric system
