Additional information

Speed is a fundamental concept in physics that measures the rate of motion or the distance covered per unit of time. It quantifies how quickly an object is moving relative to a reference point. Speed is typically expressed in units such as miles per hour (mph), kilometers per hour (km/h), meters per second (m/s), or knots, depending on the context.

The standard unit of speed in the International System of Units (SI) is meters per second (m/s).

In the US customary system, the most common units of speed include miles per hour (mph) and feet per second (ft/s).
