Question

Why is displacement referred to as a vector quantity?

Answer 1

Displacement:

1. It is defined as the shortest distance between the initial and final positions of a body.
2. It is also defined as the change in position of an object.

Vector Quantity:

1. It is a physical quantity that has both directions as well as magnitude.
2. Displacement is referred to as a vector quantity because it has both magnitude and direction.

Hence, displacement has both magnitude and direction that's why it is referred to as a vector quantity.
