* Motion is the change in position of an object over time. It's a broad term that encompasses any movement, from a snail crawling to a rocket taking off.
* Speed is a measure of how fast an object is moving. It tells us how much distance is covered in a specific amount of time.
Here's how they're related:
* Speed is a way to describe motion. It's one of the ways we can quantify how an object is moving.
* Motion is required for speed to exist. You can't have speed without something moving.
Think of it this way:
* Motion is the *fact* of moving.
* Speed is the *measurement* of how fast the movement is.
For example:
* Motion: A car driving down the street.
* Speed: The car is traveling at 60 miles per hour.
