What is dimensions of speed?

The dimensions of speed can be understood in terms of the units used to measure it. In the SI system, the standard unit for speed is meters per second (m/s). This means that the speed of an object is expressed in terms of the distance it covers in one second. Other common units of speed include miles per hour (mph), kilometers per hour (km/h), and feet per second (ft/s).

The dimensions of speed are also related to the dimensions of distance and time. Distance is measured in units of length (e.g. meters, kilometers, miles), while time is measured in units of duration (e.g. seconds, minutes, hours). Thus, the dimensions of speed can be expressed as length per unit time (e.g. meters per second, miles per hour).

It is worth noting that speed is a scalar quantity, meaning it has only magnitude and no direction. In contrast, velocity is a vector quantity that includes both magnitude and direction. While speed can be calculated by dividing the distance traveled by the time it takes to travel that distance, velocity also takes into account the direction of motion.
