# 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(Dimension.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(Dimension.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..
