Vector Multiplication вЂ“ The Physics Hypertextbook. Scalar Product of Vectors. The scalar product and the vector product are the two ways of multiplying vectors which see the most application in physics and astronomy. The scalar product of two vectors can be constructed by taking the component of one vector in the direction of the other and multiplying it times the magnitude of the other vector, The dot product is also a scalar in this sense, given by the formula, independent of the coordinate system. Examples include: Mechanical work is the dot product of force and displacement vectors, Power is the dot product of force and velocity. Generalizations Complex vectors.

The two definitions are the same. They are related to one another by the Law of Cosines. The first method of calculation is dot product. Geometrically, the dot product of two vectors is the magnitude of one times the projection of the second onto the first. The symbol used to represent this operation is a small dot at middle height (В·), which is where the name "dot product" comes from. Since this product has magnitude only, it is also known as the scalar product.

So the equation of friction will have i think cross-product and dot-product together. So it will have sin( ) and cos ( ) both in its equation. A great question by the way!!! Let me know if there are any further questions. Hope this helps Binnoy. Delete
