So every interaction does have motion in it. Both the person have to move and show their efforts to make the interaction possible.
So we do have some simple machines in our life which make our life easy and accessible. We all use simple machines so that we can do our work with fewer efforts. So what if we combine our interaction with simple machines to make them easy.
We studied some mechanism so that we can compile our work with them and make the interaction much easier. So we worked on many mechanisms to assist the kick. So we used elasticity and pulley mechanism to assist it. We faced a lot of issues with its technicalities because it was hard to choose the right mechanism that too for so dynamic interaction. If the mechanism will be loose or fragile, it can break easily on such powerful force. So we figured it out what are the possible mechanism we can use for this interaction. So we combined the interaction with a simple machine to make it easy.
