In this investigation three different variables were tested to determine their effect on the force of friction. All throughout the lab it was important to record the data found to identify how much the three variables affected the force of friction. The purpose of the first part of the lab‚ 4.1 What a Drag!‚ was to measure the force required to pull a block over five different surfaces. The sliding surfaces used in the lab were the tabletop‚ waxed paper‚ paper towel‚ fine sandpaper‚ and coarse sandpaper

gave this class a chance to help them figure out which floor matting will help a cargo box stop from moving. One factor that is used is friction. Friction happens when two surfaces rub against each other and may cause heat. Also there are four types of friction which are static‚ sliding‚ rolling‚ and fluid friction. The company needs the class to find out what type of flooring is best to use to stop a cargo box from moving. They have game systems that are imported and exported around the world

How Is Certainty Possible? Certainty is defined as being free of doubt. In philosophy is there such a thing that we know without any doubt? Do we know anything with absolute certainty? Although we may believe to have genuine knowledge in some cases‚ there are other cases in which we do not know‚ but only think we know. Now therein lies the problem‚ how do we distinguish what is absolutely certain and what is not? This is why the idea of knowledge and certainty is so important. Both empiricists
