Convert units of physical force instantly: newtons, kilonewtons, pound-force, kilogram-force, and dynes online.
In physics, force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (to accelerate). Isaac Newton formulated this relationship in his second law of motion (F = ma). The standard unit of force is the **Newton (N)**, defined as the force required to accelerate one kilogram of mass at a rate of one meter per second squared.
Structural designers, mechanical engineers, and physics students use force calculations to design structures, machines, and assess structural stress bounds.
