rörelsehastigheten
Rörelsehastigheten, often translated as speed or velocity, is a fundamental concept in physics that describes how quickly an object is changing its position. It is a scalar quantity, meaning it only has magnitude and no direction, unlike velocity which is a vector and includes both magnitude and direction. Speed is defined as the distance traveled by an object divided by the time it took to travel that distance. Mathematically, it is often represented by the formula v = d/t, where v is speed, d is distance, and t is time.
The units of speed depend on the units used for distance and time. Common units include meters
