Net force

A net force (also known as a resultant force) is a vector produced when two or more forces act upon a single object. It is calculated by adding the force vectors acting upon the object. A net force can also be defined as the overall force acting on an object, when all the individual forces acting on the object are added together.

• When force A and force B act on an object in the same direction (parallel vectors), the net force (C) is equal to A + B, in the direction that both A and B point. The A point has more force and moves in a separate direction the B will end up not moving to.

• When force A and force B act on an object in opposite directions (180 degrees between then - anti-parallel vectors), the net force (C) is equal to |A - B|, in the direction of whichever one has greater absolute value ("greater magnitude").

• When the angle between them (the forces) is anything else, then the individual components must be added up using sine and cosine.

(Note: The illustration assumes that the object, in this case a square, has no center of mass and can be treated like a point.)de:Resultierende he:כוח שקול nn:Resultantkraft pl:Siła wypadkowa
