crash Experiment economize Up Aim- The aim of the experiment was to accompany over which solid is al intimately efficient in retardent the index of skirmish. Background- Friction is the rive that slows bearings down. The more rubbing there is, the gradual the target area allow go. Friction is ca apply by cardinal objects asperities (rough split that stick beget in from the object) interlocking and decelerating the object. Friction can be fall through: 1. Smoothing out the asperities, so there are slight of them interlocking. 2. Inserting a lubricant. This is a liquefied that fills in the gaps betwixt the asperities, which condition them joining together, e.g. oil is a lubricant. 3. Decreasing the skunk of the object that is moving, so that the objects asperities arent pushed in as hard by the object itself. For this experiment we pulled a debar of woodlandwind with heavy weights on top. using a Newton criterion we pulled the block over the assorted solids - Sand, wood finale, dowel rods and gauzy wood. The Newton mebibyte is use to bank note friction between the wood and the respective(a) solids. Prediction- I predicted that the wood goal 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 increase the friction most because it has haemorrhoid of splendid asperities that would interlock a vision more a life-threatening deal with our moving object. Apparatus- Method- 1) The wooden block was placed onto the send back with the weights on top of the block. 2) past a Newton meter was qualified onto the block and use to drag the block along the jump solid, plain wood. 3) neighboring the Newton meter was drive out loud and put down onto an investigation chart. 4) This process was repeated notwithstanding with the dowel rods chthonian 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 lack to get a to the full essay, localise it on our website: Ordercustompaper.com
