Detailed explanation-2: -The newton (symbol: N) is the SI unit of force. It is named after Sir Isaac Newton because of his work on classical mechanics. A newton is how much force is required to make a mass of one kilogram accelerate at a rate of one metre per second squared.

Detailed explanation-3: -In the international system of units (SI unit) Kilogram (kg) is a unit measuring the mass of an object. Newton is a derived SI unit used to measure force.

Detailed explanation-4: -One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared. 1 N=1 kgm/s2.
