Question

difference between scalars and vectors ?

Answer 1

hello,

1.--Scalar quantity refers to the quantity, which has only magnitude and no direction.
--On the other hand, vector quantity implies the physical quantity which comprises of both magnitude and direction.

2.--scaler is One-dimensional quantity .
-- vector is multi dimensional quantity.

3.-- scaler -It changes with the change in their magnitude.
--vector-it changes with the change in their direction or magnitude or both.

4.--scaler follows ordinary algebra rules.
--vector follows rules of vector algebra.

5.Last but not the least,
--scalar quantity can divide another scalar
--but this cannot be done in the case of a vector quantity.

i hope u got it.☺

Answer 2

Answer:

1.scaler are physical quantities with only magnitude

-vector are physical quantities with magnitude and direction

2.scaler product is also known as the dot product

-vector product is also known as cross product

3.scaler obeys commuttative law

-vectors does not obeys commuttative law

4.e.g.-length,mass

-e.g.-force, velocity
