# Make it Slow Down and Stop 

Extend your C# script to slow and stop a rotating wheel in Play mode using exponential decay.

Alright, the wheel is rotating around the Z-axis. But, how do we make it stop?

In this tutorial, you'll learn how to make the slow down and stop. We'll learn how to:

- Add onto the C# script to make the wheel slow down and stop
- Play it in game mode
- & also learn how the math concept of exponential decay is connected to creating a gradual decrease in speed

## 1. Make it Slow Down and Stop

_In the Make a Spinner Project, you'll learn how to make a spinner in Unity. This is a beginner's level project and perfect for anyone who has already downloaded Unity/Visual Studio you've looked at 1-2 other Unity tutorials.
