A vector is a mathematical quantity that has both magnitude (size) and direction. It is represented by an arrow in a specific direction and length, and can be used to describe physical quantities such as velocity, force, and displacement.
Vectors are graphically represented as arrows, with the arrowhead indicating the direction and the length of the arrow representing the magnitude of the vector.
A scalar is a quantity that is fully described by its magnitude, while a vector is described by both magnitude and direction. For example, speed is a scalar quantity, while velocity (speed with direction) is a vector quantity.
To add two vectors using graphical methods, the tail of the second vector is placed at the head of the first vector. The sum of the two vectors is then represented by a new vector that starts at the tail of the first vector and ends at the head of the second vector.
A position vector describes the location of a point in space relative to an origin point, while a displacement vector describes the change in position of an object from its initial to final position.
