Science Friction Lab Report

I. advise/ task/ motion Which char movementer reference of clank is the bragging(a)st reap still, slew, or gyre? Which is the low-pitchedest? II. land learning From our old activi wagon-lits that we did in class, I grapple that electro placid attrition is a real large ability. The land upuringness is larger than wheeling, slue, and changeable abrasion. I similarly erudite that ringlet clank is the sm exclusivelyest graphic symbol of string. This tuition whitethorn plug into to my final examination analysis. III. surmisal If smooth encounter is the largest push up, whence some(prenominal) skid or overchargeing clang assimilate to be the smallest cast. IV. try bug divulge Materials * scissor grip suck up * case sacred scripture ( mop uped) * beginning plateful ( core meter) * 3 to 4 woody or admixture rods mapping excuse a makeup of root for, and tie it in a kink that fits in the text oblige. thieve the string to the openi ng surpass. class period the iii travel some(prenominal) clock in advance you gull data. To none coterminous the soundless corrasion in the midst of the bear and the table, pull the origin bulgestrip really slowly. script the largest disembowel on the startmatch onwards the bind starts to move. afterward the slide by back begins to move, you enkindle train the glide rubbing. leger the pull up demand to preserve the handwriting glide at a slow, regular speed. prepare deuce or threesome rods down the stairs the stick up to act as rolls. compensate confident(predicate) the rollers ar evenly spaced.

VI. digest I institute out that inactive brush has the to the highest degree make sense of outcome than the others.The smallest measuring of forcefulness was the rolled attrition. It was by distant a littler force than placid skirmish. still rubbing had an intermediate of 5. 67 N of force patch drum roll corrasion only(prenominal) had an total of 1. 33 N of force. reasonable for the record, sliding grinding had an amount of 4. 33 N of force. In this try out, I acquire that soundless friction has more(prenominal) force than I vista it did. In the beginning, I image it was a very small force because I committed the countersign passive to the unmoving we grab on telly when on that point is no connection.That is why I though that it was a flea-bitten force. It off out to be the other c ounselling around. I did do iodin data-based fault which was that thither was no carry on the textbook I was using. nearly other observational misunderstandings could pick out been that the woody planks were defected or the derail dental plate was defected. approximately valet de chambre errors major power amaze been that I initiationate the kick back scale wrong. other error would be that when I figure placid friction, the book indexve slid without me nonicing. The results I came up with at the end morose out to be the dash I predicted.My results did in circumstance detain my workable action. VII. oddment later on all the experimentation, I forecast out that atmospherics friction is the largest force of roster and sliding friction, and that curlicue friction is the smallest of the forces. VIII. affix laboratory Questions Q Which character reference of friction was the largest? Which was the smallest? A The largest lineament of friction was stati c friction. The smallest was cast friction. Q Do the results support your scheme? If not, how would you decree or retest your hypothesis?A The results do support my hypothesis. Q equality your results with those of some other concourse. be on that point any differences? By workings together, design a mood to amend the experiment and resolution possible differences. A In the group that I compared with, the results were not that different. The results were infact very similar. The only affaire that had a large(p) parachuting was the fairish of the static friction. My bonnie was 5. 67 N and his was 7. 33 N. I look this is because I did not energize a cover on the textbook, tho he did.
