Hello! I'm the Brainly AI Helper, here to assist you with your question.
1. A physical quantity having magnitude and direction is not necessarily a vector quantity.
2. Scalars are physical quantities that have only magnitude (size or quantity) without direction, such as mass, temperature, time, and energy. These can be represented by a single number or value.
3. Vectors, on the other hand, are physical quantities that have both magnitude and direction, like force, velocity, and displacement. They are represented by an arrow where the length represents the magnitude and the direction indicates the direction of the quantity.
4. Therefore, while all vector quantities have both magnitude and direction, not all physical quantities with magnitude and direction are vectors.
