# Collecting Data

**Acceleration:** Rate of Speed over a Short Period of time Or  the change in speed over a short period of  time

The micro:bit accelerator has the ability to track  acceleration when traveling in one direction

We have the ability to measure,  track and graph this data  as  it changes using the LED to plot  a bar graph

```
Forever
    plot bar  graph of accelleration (x) with a max of 1000
```

Now connect your battery back and go out in the hallway - move your self and your  micro bit until you can define the what X is measuring. Repeat this for Y and Z. 

**TIP**: Strength is the combined measurement of X, Y, and Z.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://computational-thinking-in-room11.gitbook.io/room-112-dhs/software-development/acceleration.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
