HELP!!!! Difference beween SCALARS and VECTORS?

Answer 1

The motion of objects can be described by words - words such as distance, displacement, speed, velocity, and acceleration. These mathematical quantities which are used to describe the motion of objects can be divided into two categories. The quantity is either a vector or a scalar. These two categories can be distinguished from one another by their distinct definitions:

1. Scalars are quantities which are fully described by a magnitude alone.

2. Vectors are quantities which are fully described by both a magnitude and a direction.

A scalar qantity has only magnitude like as:
Lenght
area
volume
speed
mass
density
pressue
temperature
energy
entropy
work
power

but a vector quantity has both magnitude and direction like as:
displancement
direction
velocity
acceleration
momentum
force
lift
drag
thrust
weight

hope this is clear to you .. have a nice time

Answer 2

Scalars have magnitude only. Temperature, speed, mass, and volume are examples of scalars.

Vectors have magnitude and direction. The magnitude of is written || v . Position, displacement, velocity, acceleration and force are examples of vector quantities. Vectors have the following properties:

1.
Vectors are equal if they have the same magnitude and direction.
2.
Vectors must have the same units in order for them to be added or subtracted.
3.
The negative of a vector has the same magnitude but opposite direction.
4.
Subtraction of a vector is defined by adding a negative vector:
- = + (- )

5.
Multiplication or division of a vector by a scalar results in a vector for which
(a)
only the magnitude changes if the scalar is positive
(b)
the magnitude changes and the direction is reversed if the scalar is negative.
6.
The projections of a vector along the axes of a rectangular co-ordinate system are called the components of the vector. The components of a vector completely define the vector.

Answer 3

I walked six miles...it truly is a scalar. I wallked six miles north...it truly is a vector. undemanding as that, a scalar with course given is a vector. A scalar without course remains a scalar. the fantastic ingredient about scalars is that you'll practice the 4 operations (upload, subtract, multiply, and divide) to them merely like you realized to do in grade college. yet because vectors continually have course besides as fee (the scalar area), even undemanding addition gained't be undemanding any more effective. as an get at the same time, if I actually have a suitable triangle with a base of three instruments and a suitable of four instruments, what do i'm getting after I upload the bottom vector to the suitable vector? the answer might want to marvel you...it is 5 at some perspective off the bottom. the bottom and suitable are vectors because they have course besides as fee. And the answer, it really is the hypoteneuse of the right triangle is likewise a vector. Vectors are very sensible in engineering and physics because forces are vectors. hence, after we are saying, F = ma we recommend a stress appearing interior the same course because the acceleration. They both are vectors.

Answer 4

Such a cute question from cute girl !The answer is very simple. There are three types of quantitys based on the things required to be mentioned to understand them. The Scalars require only magnitude as mentioning only that the distance is 5m is enough. The direction is unnecessary. But Vectors require both magnitude and direction as in the displacement is 5m due east.

Answer 5

A general high school definition you get is that a vector has a direction and a scalar does not.

A more accurate definition is that some things in this world are best represented by one value and some are best represented by three values. Direction and position in our 3-dimensional world are best described in 3 dimenions, like a vector. Temperature is best described by one value, its a scalar. Its also interesting to note that some things in this world are even better represented as 9 values; these are called Tensors.

Answer 6

Scalars have magnitude whereas Vectors have magnitude as well as direction

Answer 7

scalar is quantity with magnitude but not direction. It is a quantity, for example, mass or time, that has magnitude but no direction.

vector is a quantity with direction and magnitude. It is a quantity, for example, force or velocity, made up of components of both direction and magnitude.

hope u got it..............tried my best to help u

Answer 8

scalars require only magnitude were as vectors need both magnitude&direction

Answer 9

scalar quantities are those which are represented by magnitude alone............
example:distance.......
vector quantities are those which are represented by both magnitude and direction........
example:displacement.......

Answer 10

scalars are small, vectors are big.
