Simple example of vector field is when you do a instant picture of a room and see the tiniest particles going their way, so the velocity of them - the vector of each particle will give you a thing you need - a vector field.In other words - if you are walking, you make the particles collide with you, therefore their speed and direction can change you can make a mark in $(x,y,z)$ coordinates that velocity of particle near you is 10m/s and the direction is $(x_1,y_1,z_1)$ , and meter from you particle has such direction $(x_2,y_2,z_2)$ and speed that equals 8 m/s. Since I did my BSc in non-medical where I chose physics in my master's (MSc) and decided to deliver my knowledge to help the students in grasping the respective topics of physical sciences by having a glance at my articles. When doing any mathematical operation on a vector quantity (like . Addition of vectors means finding the resultant of a number of vectors acting on a body. The addition of these physical quantities follows the simple rules of algebra, and here, only their magnitudes are added. It consumes less power than a vector processor due to its simpler architecture.
