Question

What is difference between scalar and vector quantity
​

Answer 1

Answer:

1. Vector quantity; It is physical quantity which requires both magnitude and direction is complete description is called vector quantity. for example; displacement,velocity,force etc...

2. Scalar quantity ; physical quantity described completely by it's magnitude is called scalar quantity.for example: distance,length,mass etc ...

Answer 2

Answer:

A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.

Example:

Speed is a scalar quantity, but velocity is a vector that specifies both a direction as well as a magnitude. The speed is the magnitude of the velocity. A car has a velocity of 40 mph east. It has a speed of 40 mph.
