This article is about vectors. For the Tom Clancy sci-fi novel, see Tom Clancy's Net Force Tom Clancys Net Force is a book series, created by Tom Clancy and Steve Pieczenik and written by Steve Perry. ...

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. In physics and engineering, the word vector typically refers to a quantity that has close relationship to the spatial coordinates, informally described as an object with a magnitude and a direction. The word vector is also now used for more general concepts (see also vector and generalizations below), but this... In physics, a force acting on a body is that which causes the body to accelerate; that is, to change its velocity. ...

• 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.

• 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").

Diagram created by me for use in Net force article the size of C is OK, but it should start from the intersection point of vectors A and B, in the center of the object (about where the letter e is). ...

• 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.) In mathematics, the trigonometric functions are functions of an angle, important when studying triangles and modeling periodic phenomena. ...
