Yes. Look at the Wikipedia aritcle on "dimensionless quantity". Here are two examples:

1. Angles, when measured in radians, can be considered the ratio of the arc of a circle to the radius. The result is a dimensionless number.

2. The coefficient of friction, which is the ratio between two forces.

Dimensionless quantities often appear as a result of taking the ratio of two measurements.

Which physical quantity has negative dimension of mass?

The quantity called the Gravitational constant (G) has the following dimension: [G] = L3T-2M-1 The mass exponent is "negative" ... but watch out, it only means that mass is on the denominator ... i.e. [G] = L3 / T2M


What is more convenient to use vector quantity or the scalar quantity and why?

Scalar quantities are easier to deal with, the math is simpler. But if you have quantities that include both a magnitude and a direction, you really have no choice but using a vector quantity, to represent them correctly.


Shape is classified as a scalar or vector quantity or neither?

A scalar quantity is a physical measure of size--or extent--,while, on the other hand, a vector quantity is a physical measurement of size--or extent--AND direction. A shape has size--or extent--but does not have direction; and I would, therefore, classify it as having a scalar quantity


How is time a vector quantity?

Given that time only has one dimension, it doesn't make much sense to talk about time as a "vector". Well, technically you can have one-dimensional vectors, but those are simply called "scalars".In the Theory of Relativity, time is simply one dimension more, together with the three dimensions of space. In this case, time by itself is NOT a vector quantity, but a component of a vector quantity.


What cannot be a scalar quantity?

A scalar quantity is something that only has magnitude and no direction. Any physical quantity that has both magnitude and direction, such as velocity or force, cannot be a scalar quantity.

Is Specific charge is scalar or vector?

specific charge is because a physical quantity can be complete only when by giving magnitude only. Here the physical quantity is complete by its magnitude.

Many people believe that the physical world has only three dimensions but others have argued that Time is the fourth dimension.

Why expectation values are used?

In quantum mechanics,we are not certain about any physical quantity(unlike classical echanics).So,here value of every physical quantity can only be approximated or expected


What does it mean to say that a physical quantity is quantized or conserved?

To say that a physical quantity is quantized means that it can only take on discrete values or multiples of a fundamental unit. Conservation of a physical quantity means that the total amount of that quantity remains constant over time in a closed system, even if it may change forms.


Can a body have positive distance but negative speed?

First of all you must be familiar with scalar and vector quantities. A scalar quantity is a physical quantity having only magnitude example length. A vector quantity is a physical quantity having both magnitude and directions. Now speed and distance are both scalar quantities which means their values are always positive. But if you considered velocity then there can be a negative value. Velocity is measured w.r.t the direction the object is going. Conventionally the direction is negative if the object is moving to the left of the initial point and positive for the other way.


What is a scaler quantity?

It is a "scalar quantity", it refers to a quantity that has magnitude but no direction, as distinct from a vector quantity


What is a scalar quantity explain with eg?

A Scalar Quantity is a physical quantity which has only magnitude and no direction associated with it . For eg,mass is a scalar quantity beause it has only magnitude (say 5 kg)but has no direction in which the magnitude acts towards.on the other hand a physical quantity which has both magnitude and direction is called a vector quantity.like weight is a vector quantity because it has magnitude along with direction(i.e. it always acts in the downward direction.
