# zoomer quiz answers
Measure the acceleration on the @boardname@ in the "z" direction.
This is the answer key for the [zoomer quiz](/lessons/zoomer/quiz).
## 1. What is 'acceleration'?
Acceleration is amount of force being applied to the @boardname@ in one of three specified directions.
## 2. Consider the following directions
Write the line of code to measure the acceleration and then store in it a variable.
<br/>
```blocks
let accX = input.acceleration("x")
```
Note: acceleration does not have be measured in the "x" direction. It can also be in the "y" or "z" direction.
## 3. Consider the following directions
After storing the acceleration in a variable, write the code to show acceleration on the @boardname@ as a number
<br/>
```blocks
let accX = input.acceleration("x")
basic.showNumber(accX, 150)
```
Note: make sure the same variable name ("acc x" in this case) is the same in both lines of code..
