It has only magnitude and no direction. It depends on magnitude of two vectors which are multiplying and cosine of angle between them. A . B = AB (cosine of angle between them). Best example is 'work done by a force' = force . displacement = Fd(cosine of angle between force and displacement)

Properties Of Scalar Product
1. It is scalar
2. It is a product of two vectors
Why don't you google it dear?
A-B=4i-j+4k C.(a-b)=-2-12=-14!!!!!!!!!!!!!!!!!!!!
1) Scalar product is commutative.
2) Scalar product of two mutually perpendicular vectors is zero.
3)Scalar product of two parallel vectors is equal to the product of their magnitudes.
4) Self product of a vector is equal to square of its magnitude.
5) Scalar product in terms of rectangular components.
6) Angle between two vectors A & B can be found by scalar
product.
