Velocity (linear) is a measurement of how fast an object is moving in a straight line and in which direction. It’s a vector quantity, meaning it has both magnitude (speed) and direction.

In simpler terms, if you’re driving a car at 60 kilometers per hour (km/h) northward, then your velocity is 60 km/h in the north direction. If you’re walking at 5 meters per second (m/s) eastward, then your velocity is 5 m/s in the east direction.

Velocity is different from speed because speed only measures how fast you’re going, without considering the direction. Velocity includes both the speed and the direction of motion.
