newtons

The newton (symbol N) is the SI unit of force. It is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared, i.e., F = ma and 1 N = 1 kg·m/s^2.

Named after Sir Isaac Newton, the unit was adopted by the General Conference on Weights and Measures

In SI base units, the newton is a derived unit: 1 N = 1 kg·m/s^2. It is used
