The final result of the dot product process can be: 1  Zero: we don't have any growth in the original direction. 2  Positive number: we have some growth in the original direction. 3  Negative number: we have negative (reverse) growth in the original direction.
In Physics, as an example, Mechanical Work is a scalar and a result of dot product of force and displacement vectors. Like-wise, Magnetic flux is the dot product of magnetic field and vector area. Dot product is a scalar quantity. Watch this video that I have made to understand this better-What is Dot Product of Vectors
