Is a physical quantity having magnitude and direction necessarily a vector explain?

Statement I : A physical quantity can be regarded as a vector, if magnitude as well as direction is associated with it.

Can we have physical quantities having magnitude and direction which are not vector?

Yes, there are physical quantities like electric current and pressure which have magnitudes and directions, but are not considered as vectors because they do not follow vector laws of addition.

Is it possible that a physical quantity has direction but it is a scalar?

yes, electric current have both magnitude and direction but it is not a vector because the formula of e.c. is V/R and voltage and resistance are scalar quantities .

Are all physical quantities that have magnitude and direction?

Physical quantities which have both magnitude and direction are called vector quantities. It is represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude.

Which quantity has both magnitude and direction?

vector
vector, in physics, a quantity that has both magnitude and direction.

Should a quantity having both magnitude and direction?

Answer: A quantity which has both magnitude and direction is called vector quantities.

Which quantity do not have both magnitude and direction?

Scalar quantity is having only magnitude but no direction. Vector quantity is the physical quantity having both magnitude and direction. 2.

Which quantity has both a magnitude and direction?

vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although a vector has magnitude and direction, it does not have position.

Are physical quantities that have magnitude?

Vectors are physical quantities that possess both magnitude and direction and whose operations obey the axioms of a vector space.

Which quantity does not have both a magnitude and a direction?

Scalar Quantities
Scalar Quantities are those which have magnitude but no direction. Eg: Distance, Speed, Work, Temperature etc. Vector Quantities are those which have magnitude and direction. Eg: Velocity, Energy, Acceleration etc.

Which of the following quantities do not have both magnitude and direction?

Scalar quantity is having only magnitude but no direction. Vector quantity is the physical quantity having both magnitude and direction.

Which vector quantity has both the magnitude and direction?

velocity
Recall that velocity is a vector with both magnitude and direction. Consider the motion of a particle between two points P and Q.
