I use accelerometer for find an acceleration vs time graph from drop test. how can i find energy loss from acceleration vs time graph

thank you

Welcome to the PF.

What energy was lost? In this drop test, are you just asking how you can calculate the velocity of the object as it started to impact the platform at the bottom of the drop test? Did the object bounce? If so, do you want to calculate the energy lost per bounce?

In a drop test the accelerometer reading during travel should, ignoring noise, remain at 1; or, a net difference vs gravity of 0 until the impact.
