Which properties distinguish rhombuses from rectangles (and vice-versa?)
3. Application of parallelograms: Adding Vectors.
The forces acting on an object determine the direction in which the object will move. A force is represented by a vector, showing not only how large the force is, but also the direction in which it acts.
Each vector is given by two plane coordinates and . If two forces act on an object at the same time, then the direction in which the object will move will be given by the sum of the two vectors:
