What property of a sprite can be used to change its speed in CodeHS?

The correct answer is the property that directly influences the rate of movement of a sprite in CodeHS. In this context, the term often used to represent how fast a sprite moves on the screen is "velocity," which encapsulates both the speed and direction of the movement.

Understanding this, while “speed” may seem like a sensible option, it does not accurately describe the property used within the framework of CodeHS to modify how fast a sprite moves. The other options, like "motion" and "changeSpeed," are less commonly used in the context of sprite attributes related to speed in animations and games. They either represent broader concepts or specific functions, rather than a fundamental property influencing movement directly.
