Velocity is speed in a specific direction. It describes how fast an object moves and the direction it travels. Velocity includes both speed and direction together. It is measured in units such as meters per second.

Velocity is found in moving objects such as cars, airplanes, and flowing water. It is used in physics to describe motion in different systems. Objects on Earth and in space can have velocity.

Velocity is part of how motion is studied and described in science. It is used to compare movement in different directions. This concept is applied in many fields of study.
