SCALAR QUANTITY:- IT IS THE QUANTITY WHICH HAS ONLY MAGNITUDE BUT NO DIRECTION.

EXAMPLES:- SOUND, DISTANCE, ENERGY , POWER ETC

VECTOR QUANTITY:- IT IS THE QUANTITY WHICH HAS BOTH MAGNITUDE AS WELL AS DIRECTION

EXAMPLES:- DISPLACEMENT, VELOCITY, KINETIC ENERGY ETC

A vector quantity is a quantity that has a size as well as direction, such as a force, displacement, velocity, and acceleration.

Quantites that only have a size and no direction are scalar quantites, such as money, temperature, energy, time, length, density, and charge.

scalar quantity :

it a quantity that has no direction. it has only magnitude.

ie, like the weight of an object. it has no direction, only magnitude.

some eg. for scalars are : mass of an object.

vector quantity :

it is a quantity that has both direction and magnitude.

some egs are : acceleration,

A vector is a quantity with both magnitude (strength) and direction. Like a force having a strength in pounds and a direction. Or a wind having magnitude (in mph) and direction (Northeast). A scalar has only magnitude. Like the length of a segment or amount of peanuts in a jar. Scalars are just numbers.
