2. Finding the information • Website: http://encarta.msn.com/encyclopedia_761569794/Friction.html • Website: http://en.wikipedia.org/wiki/Lubricant 3. Using the information a) http://encarta.msn.com/encyclopedia_761569794/Friction.html Summary: Friction, force that opposes the motion of an object when the object is in contact with another object or surface. Friction results from two surfaces rubbing against each other or moving relative to one another. It can hinder the motion of an object or prevent an object from moving at all. The strength of frictional force depends on the nature of the surfaces that are in contact and the force pushing them together. This force is usually related to the weight of the object or objects. In cases involving fluid friction, the force depends upon the shape and speed of an object as it moves through air, water, or other fluid.

b) This source is accurate and reliable because it is written by a PhD (professor of physics) and is published in all Encarta encyclopaedias. Encarta provides encyclopaedias on digital format which is used around many schools. Due to this, the information has to be checked and only when it has thoroughly been examined and is relevant to the question, they publish it. It was published in 2005 making it fairly recent, and the language is easy to understand and informative. The source is accurate because of its writer, and the importance that right information is supplied throughout the world. The standards are high due to the mass use of this encyclopaedia. 4. Evaluate http://encarta.msn.com/encyclopedia_761569794/Friction.html This source will be useful to answer the assignment question because it contains information on friction, examples of friction and a separate section on how to reduce it. By knowing how to reduce it, it indirectly shows what the effect is on friction. The reliability and accuracy is bound to be found due to it being one of the most popular and widely used digital encyclopaedia around the

world. It will assist the answering of the question due to highly revised standards. The only downside will be that it is a free encyclopaedia which provides limited information about the subject, however it still provides around 75% of available information. This source has helped in answering the question with its organisation and the revised and accurate information
