... The origin of the The metric unit of force, the newton, relates force and motion. One newton equals newton 1 kilogram multiplied by 1 meter per second squared. This means that a force of one newton causes a 1-kilogram mass to have an acceleration of 1 m/sec2. In talking about force, “newton” is easi ...
