Friction Experiment Write Up Aim- The aim of the look into was to watch over which solid is most efficient in slowing the index of clangor. Background- Friction is the force that slows butts down. The more rubbing there is, the gradual the object will go. Friction is caused by two objects asperities (rough split that stick come in from the object) meshwork and decelerating the object. Friction can be lessened through: 1. Smoothing egress the asperities, so there are less of them interlocking. 2. Inserting a lubricant. This is a liquid that withdraws in the gaps betwixt the asperities, which s kick the bucket them joining together, e.g. vegetable oil is a lubricant. 3. Decreasing the skunk of the object that is lamentable, so that the objects asperities arent pushed in as hard by the object itself. For this experiment we pulled a freeze down of timberwindlandwind with heavy weights on top. Using a Newton round we pulled the block over the various solids - Sand, wood polish, dowel pin rods and nude 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 augment 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 the block a long the jump solid, plain wood. 3) Ne! xt the Newton meter was read out shouted 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
