Abstract
The objective of this report is to investigate the effects of mass, surface area and speed of a moving object on force of kinetic friction as underlined with the research question as “How do mass, surface area and speed of moving object affect the force of kinetic friction?” Therefore, the method employed in this research has three parts: In Part A, effect of mass is investigated using 1 to 15 wooden blocks that are put on top of each other and on the same surface area in each trial. Initial push was given to the blocks, and the acceleration was recorded with the help of Lab Quest Interface and Vernier Accelerometer. In Part B, effect of surface area is investigated using 6 wooden blocks that are put in variety of surface areas in each trial. Again, initial push was given to the blocks, and the acceleration was recorded with the help of Lab Quest Interface and Vernier Accelerometer. In Part C, effect of speed is investigated using a shoebox, in which there is a certain mass, which is fastened to a treadmill, and speed of the treadmill was increased up to 25ms-1. Lab Quest Interface and Vernier Force meter was used in measuring the force exerted on the shoebox. The results show that mass has a direct proportional effect on force of kinetic friction, while surface area has no effect; and as speed increases, force of friction first begins to increase but then decrease.
