👉 Svelteness is a metric used in physics to measure the rate of change of an object's velocity. It is defined as the ratio of the magnitude of the velocity change over time, or alternatively, it can be defined as the absolute value of the derivative of the velocity with respect to time. In simpler terms, svelteness measures how quickly something changes its velocity. For example, if a car starts moving at 10 km/h and slows down at a rate of 5 km/h
