Answer 1

Answer:

Scalar quantities are quantities that are described only by a magnitude. They do not have a direction of action.

Example : For fluids the relevant scalar quantities are • temperature T , measured in K.

Vector quantity has both magnitude and direction.

Example : Acceleration, Force, Moment I'm

A zero vector, denoted by a dot (.) , is a vector of length 0, and thus has all components equal to zero.

equal vector - Two ormore vectors are said to be equal when their magitude is equal and direction is same.

negative vector - Two vectors are equal but opposite in direction, then both vectors are negative of each other.

Collinear vectors - The vectors which lie along parallel lines.

Coplanar - three or more vectors lying in the same plane.

position vector - it denotes the position of the object or the point in a Cartesian plane.
