The two ways of representing numerical values of physical quantities are through scalar quantities and vector quantities.
1. Scalar Quantities: Scalar quantities are those physical quantities that have only magnitude and no direction. These include quantities such as temperature, mass, length, time, speed, and energy. Scalar quantities are represented by a numerical value followed by the appropriate unit of measurement. For example, a temperature of 30 degrees Celsius, a mass of 2 kilograms, or a length of 5 meters are all examples of scalar quantities.
2. Vector Quantities: Vector quantities are those physical quantities that have both magnitude and direction. These include quantities such as displacement, velocity, force, and acceleration. Vector quantities are represented by a numerical value, unit of measurement, and a specified direction. The direction is usually indicated using arrows or by specifying an angle with respect to a reference axis. For example, a displacement of 10 meters towards the east, a velocity of 20 meters per second at an angle of 45 degrees above the horizontal, or a force of 50 Newtons towards the north are all examples of vector quantities.
