A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight. The other way of differentiating these two quantities is by using a notation.

A vector quantity has both magnitude and direction. Acceleration, velocity, force and displacement are all examples of vector quantities. A scalar quantity has magnitude, so the direction is not important, (examples include speed, time and distance). A scalar can also have sign (such as work done and charge).
• Jul 21, 2017 · Vector quantity is any quantity that has magnitude and direction. For example velocity is a vector quantity but a similar term speed is a scalar quantity. Magnitude means the the numbers that are found as a result.
• Scalar quantity – any quantity with magnitude only → speed v = 25 m/s → time t = 14 s → mass m = .074 kg → Temperature T = 25ºC. Scalar quantities may be added, subtracted, multiplied, & divided using scalar (basic) math. Vector quantity – any quantity which has both magnitude and direction. → velocity. v.
• Jul 10, 2010 · In this example, the [3 4] is a vector quantity while the 2 is a scalar quantity. The 2 simply multiplies the magnitude of whatever you want it to multiply: it carries no direction information on its own. The vector quantity [3 4] carries a direction information (53.13 deg.). Note that the direction of [6 8] is also 53.13 degrees.

Jul 17, 2015 · The scalar product between two vectors yields a scalar quantity. Geometrically, this quantity is equal to the product of the magnitude of one vector’s projection on the other and the magnitude of the “other” vector: Using the components of vectors along the Cartesian plane, we could obtain the scalar product as follows. If the vector and ...

The quantity is either a vector or a scalar. These two categories can be distinguished from one another by their distinct definitions: Scalars are quantities that are fully described by a magnitude (or numerical value) alone. Vectors are quantities that are fully described by both a magnitude and a direction.

20 Examples of Vector quantities and scalars quantities 2 years ago The scalar quantities are those representable by a numerical scale, in which each specific value accuses a greater or lesser degree of the scale. Eg temperature, length.

In fact, whenever we come across an irrotational vector field in physics we can always write it as the gradient of some scalar field. This is clearly a useful thing to do, since it enables us to replace a vector field by a much simpler scalar field. The quantity in the above equation is known as the electric scalar potential.

vector is always positive and is a scalar. A scalar is a quantity that does not depend on the rotation of the coordinate system. Other examples of scalar quantities are mass and temperature. A number is also a scalar. Multiplying a vector by a scalar When you multiply a vector by a scalar, you multiply each component by that scalar.

Scalar quantities are those physical quantities that are expressed only by their magnitude whereas vector quantities require both magnitude and direction to completely express them. Thus, the difference between scalar and vector quantity is the presence of 'direction'.

vector: A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity.
