Velocity measurement refers to the process of determining the speed and direction of an object in motion. It is commonly expressed in units such as meters per second (m/s) or kilometers per hour (km/h). Various tools and techniques, including radar guns, GPS devices, and speedometers, are used to measure velocity in different contexts, such as in vehicles or sports. Accurate velocity measurement is essential in fields like physics, engineering, and transportation. It helps in analyzing motion, ensuring safety, and optimizing performance. Understanding velocity is crucial for applications ranging from automotive design to aerodynamics in aviation.
