A newton is defined as $${\displaystyle \mathrm {1\ kg{\cdot }m/s^{2}} }$$ (it is a named derived unit defined in terms of the SI base units). One newton is, therefore, the force needed to 展开

Large forces may be expressed in kilonewtons (kN), where 1 kN = 1000 N. For example, the tractive effort of a Class Y steam train locomotive and the thrust of an F100 jet engine are both around 130 kN.
