1.A vector quantity is a quantity which is fully described by both magnitude and direction. On the other hand, a scalar quantity is a quantity which is fully described by its magnitude.
2.Examples of vector quantities which include displacement, velocity, acceleration, and force. Each of these quantities are unique in that a full description of the quantity demands that both a magnitude and a direction are listed.
3.Vector quantities are often represented by scaled vector diagrams. Vector diagrams depict a vector by use of an arrow drawn to scale in a specific direction.
4.There are several characteristics of this diagram which make it an appropriately drawn vector diagram.
4.1.A scale is clearly listed
4.2.An arrow (with arrowhead) is drawn in a specified direction; 4.3.Thus, the vector has a head and a tail.
4.4.The magnitude and direction of the vector is clearly labeled.
5.The magnitude of a vector in a scaled vector diagram is depicted by the length of the arrow. The arrow is drawn a precise length in accordance with a chosen scale.
