Speed is measured as the ratio between the distance and time and the SI unit of speed is m/s. It is the change in the position of an object with respect to time. There are four types of speed: uniform speed, variable speed, average speed, and instantaneo
Speed is a derived property of a moving object by calculating the distance the object has moved within a single unit of time. The speed of a moving object can be expressed as a formula: v = d/t, where v represents the speed, d represents the distance the object has moved, and t rep...
What is the formula for velocity? Vector Form of Speed: The quantities such as mass, speed, electric current, velocity, acceleration, etc. are classified into two categories. These categories are vectors and scalars. The vectors are such type of quantities which are defined completely if we kno...

In Physics, a quantity can have different units as long as they are dimensionally consistent (i.e. mathematically the same). For example, the SI unit for distance is the meter although the mile is also a unit for distance. To make measurements familiar to people in different countries (e....
