Tiboelectric Series Lab (Fleur Vande Kerckhove 9A)
Tiboelectric Series Lab Fleur Vande Kerckhove 9A
Purpose/Aim:
How do the triboelectric series from different materials classify themselves due to their affinity (gaining or losing) when being measured by a gold leaf electroscope?
Hypothesis:
If the materials change (from: wool, rabbit fur, cotton, aluminum, nylon, amber, celluloid, silver, silicon and acrylic) to classify their affinity of their triboelectric series then rabbit fur will have a higher affinity compared to the rest of the materials. By rubbing an object against another object, there is a process of charging an object due to friction. When these two different materials are rubbed together, one material’s surface will technically remove some electrons from the surface of the other …show more content…
In order to keep the experiment testable and fair it is important that the time that the material is being rubbed on the appropriate material (of the trial) is controlled. If the time that the each material is being rubbed on differs from each other, the results at the end of the experiment will not be truly valid and testable for a valid conclusion. To control the amount of time the material is being rubbed on the appropriate material, there will be a timer set that goes up to one minute. As the timer starts, the rubbing starts on both materials (against each other). When the timer ends after exact one minute, no movement of rubbing on the both materials should be detected at …show more content…
It is important that with every material that is being tested (10 in total) maintains the same amount of trials. Every material has ten materials to rub with (see trial chart on pages 9-13). If this variable is not controlled and materials don’t get rubbed with every material then the data table (see sample on page…) will be uncompleted and unsuccessful with invalid and unfair data. In order to keep this variable controlled every material is going to be rubbed by all of the materials that are going to be tested (see trial chart on pages 9-13). During this experiment, this trial chart must be
