An investigation into the relationship between distance and sound

The aim of the experiment is to find the relationship between the distance and the sound, produced between an elastic band and a wall. The will be done by pulling back an elastic band at a different distance each time and shooting it at the wall and then recording the sound it produced using a speed level meter.

Pulling back an elastic band with an increasing distance each time and then shooting it at the wall will result in increasing speed in which the elastic band would go. This would mean that the kinetic energy would increase too because the theory of the kinetic energy states that the kinetic energy is proportional to the speed squared. But as the elastic band hits the wall all the kinetic energy gets lost either in the form of heat or sound. So, the more kinetic energy there is the more sound would occur. Thus, it can be predicted that as distance increases the kinetic energy increases.

In this lab the manipulated variable would be the distance of the elastic band that is pulled. The speed and time would also
