Question

Define scalar and vector quantities. Give some examples.

Answer 1

Scalar Quantities:

1. Scalar quantities are defined as the physical quantities with only magnitude and no direction.
2. For example, mass, distance, time, speed, density, etc.

Vector Quantities:

1. Vector quantities are defined as the physical quantities that have magnitude as well as direction.
2. For example, displacement, force, velocity, acceleration, etc.

Hence, scalar quantities have magnitude and vector quantities have both magnitude and direction.
