Physics - Kinematics - Vectors
Vectors Certain physical quantities can be described by only a numerical value or numbers completely. Such quantities are called scalar quantities. Examples of scalar quantities are speed and distance as they are related to only magnitude.\ Some physical quantities need both direction and magnitude to be described completely. Such quantities are vector quantities. Examples are velocity and displacement. Vectors also follow the triangle law of vector addition. Representation of vectors :- This is the representation of vectors diagrammatically. The front end is the head and the rear end is the tail. It is written as shown in the image above and also like this in bold letters. " AB" . In this blog, we will use bold letters to represent vectors. The point where to the particle is going or moving comes after the first letter. Here, A is written before B. Vectors can be shifted paralle...
