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.

Is distance a vector quanity?
It can be both true or false - you can treat distance as a scalar, or as a vector. If you say that (say) the distance from the cities of Cochabamba and Quillacollo is 13 kilometers - WITHOUT specifiying the direction - then it is a scalar. If you also say that Quillacollo is to the east of Cochabamba, then it is a vector.
Why is speed classified as a scalar quantity and velocity classifed as a vector quantity?
Vectors have speed AND direction. Speed is classified as a scalar quantity because it only has magnitude (numerical value and unit of measurement) such as 50 mi/h. Velocity is classified as a vector quantity because it has magnitude and direction, 50 mi/h north. By including direction, you are giving more information than a scalar quantity (requiring one unit).
Is weight scalar or vector quantity?
scalar, produced by the scalar product of two vector quantities ... Force · Distance
What is vector and scalar quantities?
A vector quantity is a quantity that has both magnitude and direction. Velocity, acceleration, and force are examples of vector quantities.A scalar quantity is a quantity that has magnitude, but no direction. Time, mass, volume, and speed are examples of scalar quantities.
How many components have a vector?
It is the other way round - it's the vector that has components.In general, a vector can have one or more components - though a vector with a single component is often called a "scalar" instead - but technically, a scalar is a special case of a vector.

Is frequency a scalar or vector quantity?
Frequency is a scalar quantity,now comes the question how to decide which one is scalar and which one is vector,scalar quantities are those which only have values and we can't assosciate any direction to them ,whereas,vector quantities are those which have values as well as directions assosciated with them.For example,time is a scalar quantity because we say its 10:30 pm we never say its 10:30 pm south-west,where as if we say the wind is blowing at 30 m/sec towards north(this particular thing is called velocity)then it is a vector quantity. some more examples:-300 degree celcius(scalar),76.8%(scalar),5 meters north(vector)
What is it called when a scalar and a vector are multiplied together?
When a scalar quantity(if it has positive magnitude) is multiplies by a vector quantity the product is another vector quantity with the magnitude as the product of two vectors and the direction and dimensions same as the multiplied vector quantity e.g. MOMENTUM

Is area a vector or a scalar quantity?
it's a rather puzzling idea, but area can be either a scalar or vector quantity. Usually area is a scalar quantity. E.g. the area of my house is 2000 square feet. In more advanced calculus courses you'll run into area vectors. area is a vector because as u know pressure=force/area which is scalar"pressure"=vector"force" / X"area" area"X"= force/pressure which is vector/scalar =vector so area is a vectorIn geometry, for a finite planar surface of scalar area S, the vector area : is defined as a vector whose magnitude is S and whose direction is perpendicular to the plane, as determined by the right hand rule on the rim (moving one's right hand counterclockwise around the rim, when the palm of the hand is "touching" the surface, and the straight thumb indicate the direction). :
Is time a vector or scalar quantity?
Time is a scalar quantity. And any interval of time is also scalar. It has magnitude only. A vector quantity is a scalar quantity that has the added or extra "dimension" of direction. Time has magnitude, but is not considered to have direction as such. Time, though it can be "tricky" to deal with in quantum mechanics, is generally thought of as moving "forward" and generally cannot more in another direction. (Save the "exceptions" for more advanced physics, please.) Time travel is relatively impossible now, but if you graphed time, you would see a parabolic motion.
Is weight scalar or vector quantity?
scalar, produced by the scalar product of two vector quantities ... Force · Distance
Is gravity is scalar or vector quantity?
Gravity is a vector, because it is a form of acceleration (which we know by definition is a vector). Vectors hold more 'information' than scalars, because vectors are, put simply, a scalar + a direction. To help you figure out these types of questions in the future, all you have to do is figure out whether direction is an important aspect of the value in question.

Is electric potential difference a vector?
We generally think of electric current as a scalar quantity. When we think of 1/4th amp or 20 amps, we think of an amount (a scalar quantity) of current flow. On another plane, the electromagnetic forces at work in current generation are actually force vectors. In the traditional sense, electric current, which is the movement of electrons, is from negative to positive. This is not a vector, though. In the macro or "large" world, think of current as scalar.---------------------------------------------------------------------The beauty is that though current is not a vector definitely its direction of flow is used to make length as vector. I is not vector. dl is not vector but I dl will be considered as vector. So innovative and essential concept.Current density is a vector which appears in Maxwell's equations.
What is a vector quatinty?
A vector is a part of a more general number or quantity, called a Matrix or Quaternion. Vectors were developed by William Rowan Hamilton as part of a Quaternion. The Quaternion consists of a scalar part 1 and three vectors I ,J and K.. The scalar is a real number and InJ and K are vector numbers, where I^2 = J^2 = K^2 = -1.. Vectors denote directions such as an axis in space, Ix + Jy + Kz. Quaternions Q = s + V = Q(cos(Q) + Vsin(Q)) = [cos(Q), sin(Q)(I + J + K)] . The Quaternion is vector if the angle is an even multiple 90 degrees and the Quaternion is a vector when the angle is a odd multiple of 90 degrees.. If the angle is not a multiple of 90 degrees, the Quaternion is part scalar and part vector. Most variables in physics are Quaternions. ============================================ A 'vector' quantity is a quantity that has both a size and a direction. Examples are: force, velocity, acceleration, and electric field. A 'scalar' quantity is a quantity that has size but no direction. Examples are: cost, temperature, speed, and volume.
