Scalers and Vectors: Learn about scalers and vectors

The video tutorial explains the concepts of scalars and vectors in physics. Scalars are quantities with magnitude but no direction, exemplified by pressure and temperature. Vectors, on the other hand, have both magnitude and direction, with examples including velocity and magnetic fields. The tutorial also covers how vectors are represented using arrows, where the length indicates magnitude and the direction of the arrow shows the vector's direction.
