Friction Experiment Write Up Aim- The aim of the look into was to watch everywhere which solid is most efficient in slowing the index of skirmish. Background- Friction is the force that slows determinations down. The more crash there is, the gradual the object will go. Friction is caused by two objects asperities (rough split that stick come in from the object) mesh and decelerating the object. Friction can be lessened through: 1. Smoothing kayoed the asperities, so there are less of them interlocking. 2. Inserting a lubricant. This is a liquid that gormandizes in the gaps betwixt the asperities, which s surmount them joining together, e.g. crude is a lubricant. 3. Decreasing the skunk of the object that is pathetic, so that the objects asperities arent pushed in as hard by the object itself. For this experiment we pulled a blockage of woodwind instrumentwindlandwind with heavy weights on top. Using a Newton molarity we pulled the bloc k over the various solids - Sand, wood polish, jiggle rods and out-and-out(a) wood. The Newton meter is used to bank note friction between the wood and the various solids. Prediction- I predicted that the wood polish would decrease the friction most as it acts as a lubricant to fill in the asperities between the objects.

I and so predicted that the sand would add the friction most because it has haemorrhoid of small asperities that would interlock a lot more a good deal with our moving object. Apparatus- Method- 1) The wooden block was placed onto the table with the weights on top of the block. 2) Then a Newton meter was qualified onto the block and used to drag t he block along the jump solid, plain wood. ! 3) Next the Newton meter was read out clamorously and recorded onto an investigation chart. 4) This process was repeated notwithstanding with the dowel rods under the block, then the sand was used and then cleaned away. Lastly, the wood polish was sprayed and rubbed into the asperities. These finds were all recorded onto the chart infra: lubricant| Friction(n)1| Friction(n)2|...If you want to get a full essay, localise it on our website: OrderEssay.net
