What was the diffrence between vector and scaler quantity??.With examples

Answer:
The Difference Between Vector And Scalar Quantities-
The scalar quantity is defined as the quantity that has only got magnitude, but not directions whereas, vector quantity comprises of both magnitude and directions.
The scalar quantity is only one dimensional and vector quantity is multi-dimensional.
Scalar quantity changes if its magnitude changes, but vector quantity changes when magnitude or direction or both changes.
There are normal algebra rules for the scalar quantity and also for vector quantity there is separate vector algebra.
The scalar quantity can divide another scalar quantity, but in case of the vector quantity, two vectors cannot be divided.
Some of the examples of scalar quantities are mass, volume, charge, speed, time and electric potential. The distance between the two points in the space is the scalar quantity, but not its direction. Also, velocity is a vector quantity, because it is the measure of the rate of an object changing its position.
A vector is represented by an arrow above any quantity. If a vector represents the quantity in a single direction like X-direction( left or right), y-direction ( up and down), then the vector quantity is written as the number with + or – sign in front of it. The + sign indicates the direction of quantity in the right or up direction, and – sign indicates that the vector quantity is in left or down direction. Also, in the two-dimensional space, the vector represents the magnitude and the direction.
Hope it helps u can make short
Answer:
scalar quantity need only magnitude to describe them
eg. mass, volume,power, speed
vector quantity need both magnitude and direction to describe them
eg.force, momentum, velocity, acceleration, displacement
