Should a quantity having magnitude and direction necessarily be a vector?

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

What is the vector quantity having both magnitude and direction?

Answer: A quantity which has both magnitude and direction is known asvector quantity.

Which quantity has both magnitude and direction but not a vector quantity?

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 . and two scalar quantities can never give a vector quantity . and it follows simple algebra rules.

What are the examples of vector quantity?

Examples of vector quantities include displacement, velocity, position, force, and torque.

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.

What is a quantity with magnitude only?

A quantity which does not depend on direction is called a scalar quantity. … Scalar quantities have only a magnitude. When comparing two vector quantities of the same type, you have to compare both the magnitude and the direction. For scalars, you only have to compare the magnitude.

What is magnitude of a vector quantity?

The magnitude of a vector is its size. It can be calculated from the square root of the total of the squares of of the individual vector components.

What does magnitude of a vector quantity mean?

length
The magnitude of a vector is the length of the vector. The magnitude of the vector a is denoted as ∥a∥. … For a two-dimensional vector a=(a1,a2), the formula for its magnitude is ∥a∥=√a21+a22.

What are scalar quantities give examples?

scalar, a physical quantity that is completely described by its magnitude; examples of scalars are volume, density, speed, energy, mass, and time. Other quantities, such as force and velocity, have both magnitude and direction and are called vectors.

What is magnitude and direction?

A vector contains two types of information: a magnitude and a direction. The magnitude is the length of the vector while the direction tells us which way the vector points. Vector direction can be given in various forms, but is most commonly denoted in degrees. Acceleration and velocity are examples of vectors.

What is magnitude in scalar quantity?

Scalar quantities only have magnitude (size). For example, 11 m and 15 ms –1 are both scalar quantities. Scalar quantities include: distance. speed.

Which quantities indicate a direction and a magnitude?

A vector is any quantity with both magnitude and direction. Other examples of vectors include a velocity of 90 km/h east and a force of 500 newtons straight down. The direction of a vector in one-dimensional motion is given simply by a plus ( + ) or minus (−) sign. Vectors are represented graphically by arrows.

What’s the difference between vector and magnitude?

vector: A directed quantity, one with both magnitude and direction; the between two points. magnitude: A number assigned to a vector indicating its length.

Does magnitude include direction?

Magnitude is the quantitative value of seismic energy. It is a specific value having no relation with distance and direction of the epicentre. We can say that magnitude is the size of an earthquake.

Which quantity has both magnitude and direction choose the correct answer?

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

Which of the following is a vector quantity?

Detailed Solution. The Correct Answer is Velocity. Velocity is a vector quantity.

Is position a vector quantity?

The position is a vector quantity as it has both magnitude and direction.

Which of the following is a quantity that has both magnitude and direction a velocity B mass C density D volume?

Answer: Vector Quantity: A physical quantity is said to be a vector quantity when it has both magnitude and direction. The scalar quantities are distance, mass, time, volume, density, speed, temperature, and energy, The vector quantities are weight, velocity, acceleration, and force.

Is a vector quantity?

A vector is a quantity that has both a magnitude and a direction. Vector quantities are important in the study of motion. Some examples of vector quantities include force, velocity, acceleration, displacement, and momentum.

Does momentum have direction and magnitude?

momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.

Which has magnitude as well as direction?

Force has a well-defined magnitude as well as direction.

Which of the following electrical quantity has magnitude and also which changes its direction periodically?

Electric current is a scalar quantity but it possesses magnitude and direction.

Which of the following gives both direction and magnitude a scalar B vector C both D none?

b) vector is the correct option.
