what is vector quantity and scalar quantity?

Answer 1

a quantity which has direction and magnitude is a vector . velocity,acceleration are good examples .
a quantity which has only magnitude is a scalar . speed is example
well if somebody tells u the speed of the body is 10m/s then u cant ask in which direction.can u?
consider a body moving in a circular motion,then acceleration is towards the center,at the same time it is accelerating with xm/s2 so it has both direction and magnitude.suppose u say its accelerating with xm/s2 then the opponent can raise u this question ,which is the direction so u would be answering towards the center .

Answer 2

A vector quantity is a physical quantity which has both magnitude and direction whereas a Scalar quantity has only the magnitude but no direction

Answer 3

vector quantities are those physical quantities which have both magnitude and direction.eg. velocity,force etc.
mind it these quantities follow the vector laws of addition.
current though is associated with its direction of flow,is a scalar quantity since it follows simple addition.

scalar quantities are those which have only magnitude.
eg:mass,speed etc

Answer 4

A scalar quantity denotes only the actual magnitude. Whereas, a vector quantity denotes both magnitude and direction.
Examples for vector are force, acceleration, velocity etc..,
for scalar:- speed, density, mass etc..,

Answer 5

The physical quantities which are completely described by magnitude (size) alone are called scalar quantity.
EX. Mass, Length,Time,Density,Speed etc.
The physical quantities which are completely described by magnitude and direction are called vector quantity.
EX.Velocity,Force,Weight,etc.

Answer 6

a scalar quantity is a physical quantity that has only a magnitude, no direction. eg mass, volume, etc
a vector quantity has a magnitude, a direction and follows triangle law of vector addition(or parallelogram law of vector addition)
this is probably why time is not treated as vector even though it has a direction

Answer 7

vector quantity are those quantity which have magnitude and direction both and also can be added by triangle law of vector
examples-force,velocity
scalar quantity only have magnitude no direction
examples-mass,distance

Answer 8

scaler quantity are those which have magnitude but no direction.ex-speed.

vector quantity are those which have both magnitude and direction.ex-velocity.

these above quantity have same units but uniform speed do not mean uniform vel bcoz if a particle moves with same speed but in different direction then velocity will change.

Answer 9

scalar - only magnitude

vector - magnitude and direction

Answer 10

WELL THE ANSWER IS

(SCALER QUANTITY)-- having magnitude,and direction......

(VECTOR QUANTITY)--having magnitude, no direction
