No, speed is not a vector quantity; it is a scalar quantity.
Speed refers to how fast an object is moving, regardless of the direction of that movement. It is defined as the distance traveled per unit of time and is expressed in units such as meters per second (m/s) or kilometers per hour (km/h). Since speed only has magnitude and does not incorporate direction, it is classified as a scalar.
In contrast, velocity is a vector quantity, which means it includes both magnitude and direction. For example, if a car is traveling at a speed of 60 km/h to the north, its speed is 60 km/h (a scalar), while its velocity is 60 km/h north (a vector). Understanding the distinction between speed and velocity is important in physics, particularly when analyzing motion.
