Question

what is scalar product and vector products

Answer 1

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 scalar product is also called the "inner product" or the "dot product" in some mathematics texts.

Answer 2

scalar product is a property which can be described only by my magnitude . example :distance ,mass,temperature ,etc...
vector product is a quantity which is described by both magnitude and direction . geometrically a vector can be a line segment . example :force
velocity ,displacement etc...
