# Collecting Data

Microbit and Battery Pack

**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.
