👉 Rapidity is a physical property of an object that describes how quickly it moves. It is measured in meters per second (m/s) and can be defined as the ratio of velocity to time. The definition of rapidity is: ``` r = v/t ``` where: - `v` is the velocity of the object, - `t` is the time elapsed. Rapidity measures how quickly an object moves, regardless of its shape or size. It can be used
