# Speed/Velocity Unit Converter

Last updated: Saturday, April 29, 2023

Speed and velocity both refer to how fast an object is moving, but they have different meanings in physics.

Speed is a scalar quantity that represents how fast an object is moving in a particular direction, regardless of the direction. It is measured in units such as meters per second (m/s), miles per hour (mph), or kilometers per hour (km/h). For example, if a car travels 100 km in 2 hours, its speed is 50 km/h.

Velocity, on the other hand, is a vector quantity that represents both the speed and direction of an object's motion. It is measured in the same units as speed, but with an additional direction component. For example, if a car travels 100 km due north in 2 hours, its velocity is 50 km/h north.

In other words, velocity describes not only how fast an object is moving, but also the direction in which it is moving. If the direction changes, the velocity changes even if the speed remains the same. For example, if a car travels around a curve in the road at a constant speed, its velocity is changing because the direction is changing.

Both speed and velocity are important concepts in physics and have applications in many fields, including transportation, engineering, and sports.

The SI unit of Speed/Velocity is meter / second [ m / s ]
