A Velocity Calculator is a tool used to determine the velocity of an object, which is the speed of the object in a specific direction. It typically requires inputs such as distance traveled and the time taken to cover that distance. The formula used is velocity = distance/time, allowing users to quickly find out how fast something is moving. These calculators can be found in various forms, including online tools and mobile applications. They are useful in fields like physics, engineering, and sports, helping professionals and students alike to analyze motion and improve performance in activities related to physics, engineering, and athletics.
