accelerometer & gyroscope data analysis for frequency and magnitude

I have data from a Nintendo Joycon accelerometer & gyroscope that looks like this. The data is collected every 100 MS and a time stamp is put beside each of the rows. I would like to be able to find the frequency and the magnitude of the movement (preferably in 10 second intervals). I have never worked with accelerometer data and any help would be greatly appreciated- whether it is code you have that is similar or ideas on how to do this. Thank you!!!

I'm about to do something similar. How do you read the joycon data into MATLAB?

Read about fft.
