This real life application deals with how the Wii remote works and how this relates to real life applications. Most students will get a kick out of this discussion. The main thing I like to relate it to is Newton's first law. An object in motion will remain in motion unless acted on by an outside force. In this case tiny rods that shift, due to inertia, causing changes in voltage which are compared to a database of similar shifts so that the console knows what move is being made. Then, I bring in the second law. If there’s a force then there must also be an acceleration (Newton’s second law). This is why measuring device in the Wii remote is called an accelerometer and not a velocimeter. So every time the remote changes its motion the accelerometer picks it up.
