Answer
The unit of force in the International System of Units (SI) is the newton, abbreviated as "N." The newton is named after Sir Isaac Newton, and it is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. Mathematically, one newton is equal to:
1N=1kg⋅m/s2
In other words, if a force of one newton is applied to an object with a mass of one kilogram, the object will experience an acceleration of one meter per second squared.
The newton is a derived unit in the SI system and is used to quantify forces in various scientific and engineering applications. Other non-SI units, such as the dyne or pound-force, are also used in specific contexts, but the newton is the standard unit for force in the SI system.
