| Procedure: |
After determining the mass of the car
(.0617 kg) and the length of the incline (.50 cm) (or at least the
start and finish marks on the incline), it was decided that in order
to perform the experiment properly, the car had to have added weight
(.0020 kg), because the weight hanger was to heavy to allow the car to
reach equilibrium.
The plane was then set to 10o with the height of the angle at .086 cm. The empty hanger weight is .0148 kg with another .002 kg added (.0168 kg total) to achieve the necessary effect on the car. The car took a steady, constant course to the top of the incline and performed .054 J of work with a kinetic coefficient of .091. Next, the angle of the incline was set up to 20o and the weight increased to accommodate the change. The next 5 stages also included angle adjustments and weight increases that produced results that reflected an increase in values. See the chart to follow each step to it's fruition. Finally, the coefficient of the static friction was determined by laying the incline table flat and turning the car upside down to see what weight was necessary to cause a constant, steady movement of the car. The same additional weight was placed on the belly of the overturned vehicle to keep the weight consistent throughout the experiment. The coefficient of static friction in this case is .45. In each case, the work (W) equaled the potential energy (U). |

| Conclusion: | Friction can be described as the ability of a surface to adversely affect an object by restricting it's motion, thus causing heat and slower movement. On the incline car is constantly wanting to travel downward as long as there is no weight added, but in order to accomplish the goal of equilibrium, a weight is necessary. This exercise shows how much difference there is in the values obtained at different angles of incline. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
