What Is a Newton?

The newton is a unit to for measuring force equal to the force needed to move one kilogram of mass at a rate of one meter per second squared.[1]

The newton is the SI derived unit for force in the metric system. Newtons can be abbreviated as N; for example, 1 newton can be written as 1 N.

Newtons can be expressed using the formula: 1 N = 1 kgm / s2
