Speed alone can't fully describe how something moves because it doesn't include direction. That's where velocity comes in!
Velocity is more than speed; it tells you how fast something moves and in what direction.
Imagine you're riding a bike at 10 miles per hour. If you're heading east, your velocity is 10 mph east. The direction makes all the difference.
Velocity is described using vectors. Vectors are arrows that show both the speed and the direction of motion.
The arrow's length indicates the speed, and the way the arrow points shows the direction.
For example, two cars move at 60 mph, but if one goes north and the other goes south, they have different velocities.
The average velocity is calculated by dividing the net distance from the starting point by time plus the direction. For instance, if you travel 100 miles east in 2 hours, your velocity is 50 miles per hour east.
Velocity changes when an object speeds up, slows down, or changes direction.
