The attached picture sums up my experiment. I used a slinky (a kind of a bouncing spring) to see the relationship between its maximum length when released and the length of its first rebound. However, I released the slinky using various different magnitudes of force. I used a sensor (a LabQuest 2) so I know the position, velocity and acceleration of the slinky for all my data points at all times. I'm guessing the force would equal mass of the slinky times acceleration at time 0 for each data point. But how would I put that into consider in my experiment? It does need to be considered. I want to make calculations such that both lengths reflect what would happen if the slinky was dropped at a constant force for all data points.
