* Both describe how fast something is moving. They both tell you how quickly an object changes its position over time.

* Both are measured in the same units. The standard unit for both speed and velocity is meters per second (m/s), although other units like kilometers per hour (km/h) or miles per hour (mph) are also commonly used.

However, they are very different in one crucial aspect: velocity includes direction.

Here's a simple analogy:

* Speed is like saying "I'm driving at 60 miles per hour."

* Velocity is like saying "I'm driving at 60 miles per hour north."
