Discussion: Which of the materials used is best suited for a insole replacement.

Analysis of results:
As the results of my experiment shows, the insole made of Felt is the best shock absorber. This is as our hypothesis had predicted. 

Key findings:
I found out that felt would be the best replacement for an insole.

Analysis of key readings:
This is because compared to the other materials tested in the experiment, felt is able to disperse or disrupt the energy caused by shock’s impact forces, absorbing the energy from shock by decreasing the amplitude (strength) of the shock energy’s wave or by changing the wave’s frequency

Even though it may seem that to be that felt is an obvious choice, it is actually not. As felt is an entirely different material compared to a proper sport insole, which is usually made of foam. Thus, foam would have been the most reasonable choice. However, the foam tested in this project is a piece of condensed foam board, thus, the results obtained from this experiment may not have been as accurate when compared to the foam that insoles are usually made off.

The reason why felt is the best shock absorber is because felt is because of the differences in the thickness of the different material, I used multiple pieces of felt to make it the same thickness as the other materials, making only the material as the independant variable. This results in there being some air in between the different layers, allowing the pendulum to land with a bit of cushioning.

Evaluation of hypothesis:
My original hypothesis for this experiment was that felt would be the most suitable material to use as a insole replacement, and, based on the data gathered from the experiment, the hypothesis is proven to be correct.
