define scalar and vector quantities. explain with example the graphical represantation of victor quantities.
Answers
Answer:
Explanation:
What are scalar and vector quantities give examples?
Scalar Quantities: The physical quantities which are specified with the magnitude or size alone are scalar quantities. For example, length, speed, work, mass, density, etc. Vector Quantities: Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction.
Answer:
A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight
Vectors can be represented graphically as arrows. The length of the arrow indicates the magnitude of the vector. The direction of the arrow indicates the direction of the vector. ... When two vector quantities are added, the two arrows that represent the quantities are joined tip-to-tail.
