Are all physical quantities that have magnitude and direction vectors?

No. A physical quantity having both magnitude and direction need not be considered a vector. For example, despite having magnitude and direction, current is a scalar quantity. The essential requirement for a physical quantity to be considered a vector is that it should follow the law of vector addition.

Are all physical quantities vectors?

In contrast to vectors, ordinary quantities that have a magnitude but not a direction are called scalars. For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars.

Do all physical quantities have magnitude?

Yes, definitely there exists physical quantities which have magnitude as well as direction but are not vector quantities.

Which of the following quantities have both magnitude and direction?

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

Which of the vector does not have specific direction?

The zero vector has no particular direction; this is consistent with the fact that it is orthogonal to every other vector.

Which of the quantities have both magnitude and direction?

Is usually said to be a physical quantity that only has magnitude and no other characteristics?

A scalar is usually said to be a physical quantity that only has magnitude and no other characteristics such as direction. Volume, time, area and length are scalar quantities, while impulse, moment, momentum and displacement are vector quantities.

Which of the following have both magnitude and direction?

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

Which physical quantity is a vector quantity?

The physical quantities which have both the magnitude as well as the direction and which should be specified by both magnitude and direction are called vector quantities or vectors. For e.g. when we are specifying the displacement of the body, we have to specify the magnitude and direction. Hence, displacement is a vector quantity.

Is there a physical quantity that has magnitude but not direction?

Yes, definitely there exists physical quantities which have magnitude as well as direction but are not vector quantities. One such example is “Current”. It has made and direction both but still it’s not a vector quantity.

How do you find the magnitude of a vector quantity?

A vector quantity is represented with an arrow over a letter or a boldface letter. Geometrically, it is represented by a line segment, having an arrow at one end. The arrow describes the direction and the length of the segment gives the magnitude.

Are there any vectors that do not have magnitude and direction?

Vectors have been presented as things with magnitude and direction, like little arrows. You are asking for clarification on what vectors are all about. Little arrows are a good example of vectors. But yes there are vectors that do not have magnitude and direction.
