We have another question regarding the mechanics of the ADXL377 w/eval board. 
Is the accelerometer measuring the change in velocity over time or the force over mass?
Without getting too complicated, in our application the chip is fixed to the head of an individual. I provided the two formulas below.

Acceleration= Δ Velocity/ Time

Acceleration= Force/ Mass

 

Which is does the ADXL377 use?

 

Thanks,

PS. Also still need a question answered from 3/31 on maxing out the sensor over 200G
