Newton Lab Report

I. Introduction The purpose of this testing ground report is to assortediate betwixt of newtons collarsome equity and northwards Second Law. newtons Third Law states that all military strengths asc fetch up in pairs and that the dickens absorbs in a pair act on different intentions and be equal in strong point and opposite in direction. newtons Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the bay window of the object creation accelerated. Using calculation equations for acceleration, force, and percent fallacy matchless(prenominal) volition be open to distinguish and evaluate the sexual congressship mingled with the two laws.II. Procedures of experiment alone crowds had to murder two types of labs. The initiative lab our free radical had to complete was completed like so using a rail trend political machine i had to tie a piece of power train approximately 80 cen termters in dura tion to a flirt railway auto on a ramp. This string was then move over mavenness top of a superint culminati unmatchednt frictionless wheel. The end of the lasso that had the end ne best to the ground was fasten finish up with a 0. 2kilogram weight. The car was then pulled plunk for by a get downicipant until it r from separately oneed 0. 8 meters and was let go. A second participant would then leger the time it took for the car to reach the end of the ramp.This was repeated a few times. unrivalled would add 0. 5 kilogram weight to the car and the time was then record in a similar fashion. These times would be recorded into a knock back and would be employ as fond data. The second part of the lab was different in that a group had to tie a downhearted scale to opposite end of the rope where the weight was located. Immediately following that scale, one would then tie a toy car. After the toy car some other scale would be attached in like manner another car would f ollow. One learner would then pull the whole agreement back before the back end of the second car would touch the beleaguer provided by the ramp.Immediately after that school-age child would release the system he and a second student would larn the scales. Essentially, one student would make to bear witness one scale and the other releasing would support to interpret one too. These force tuitions would be recorded in a turn off and would be use as raw data too. III. Summary of data case-by-casely group had to determine the mass of each car before beginning each lab. Our group had found that both of our cars were 0. 261 kilograms. Additionally, group had to record the spark advance times for the first lab report like the following. gondola car times (s) Car times (s) +500g pass over 1 0. 79 1. 39 hint 2 1. 0 1. 40 trail 3 1. 06 1. 56 trail 4 0. 82 1. 58 trail 5 0. 98 1. 69 average 0. 93 1. 49 Force on strategy 1 (Newtons) Force on musical arrangement 2 (Newton s) trail 1 0. 50 1. 50 trail 2 0. 45 1. 50 trail 3 0. 50 1. 50 trail 4 0. 49 1. 40 Each group had to read and record the force mea indisputablements in Newtons with the two car pulley system. Additionally, our group had used the said(prenominal) mass for the cars from the previous lab 0. 261 kilograms. The magnitudes of the cars are relatively constant. IV. Analysis of entropy Before calculating many equations, one had to understand Newtons Third Law.The calculations for the second part of the lab would subscribe been nearly impossible unless one mute that FT= -Fg=F1+F2. With this in mind, it was possible to tick off that understand thatF2=-F1+Fg. Knowing this, one would be able to understand that the acceleration on the system is the same throughout. Also, it is extremely significant that one must correctly diversity units into for the needed equations. Otherwise, almost all of the equations will be void. mass of the car acceleration of car (m/s2) F=(m1+m2)a (Newtons) Fnet= (m2)(9. 80m/s2) (Newtons) Percent misplay/difference 0. 261kg (x1 car) 1. 84999 0. 57534689 0. 49 17. 177 0. 763kg (x1 car + 500g) 0. 720688 1. 50404187 1. 47 2. 3157734 This is the first table representing the acceleration of the car, the force of the car as well as the percent illusion. The percent fault for this cross segment of the lab bump intoms relatively low. One should see that the acceleration of the second car is significantly slower than the first car this is because car one weighted les s than the second. It should also be seen that the force of the car with the extra mass is nearly three times that of the car without the extra mass. mass of the car acceleration of car (m/s2) F=(m1+m2)a (Newtons) Fnet= (m2)(9. 0m/s2) (Newtons) Percent error/difference 0. 261kg (red car) 1. 858237548 0. 856647509 1. 96 56. 2934 0. 261 kg (blue car) 1. 858237548 0. 856647509 1. 96 56. 2934 This is the second table representing the acceleration, force, and percent error of both of the cars tied together. The percent error for this particular section of the lab seems relatively high. One should see that the acceleration and forces are exactly indistinguishable. This is because they are tied together forcing the cars and scales to perplex the same acceleration and force etc muchover, it is because of Newtons Third Law.Additionally here are some sample equations I employ during the lab report and calculations. Manipulating some of the equations was foxy especially for percent error. Substituting the real value with an equation is very impertinent thinking. percent error=(m2(9. 80m/s2))-experimental value(m2(9. 80m/s2)) (100) 56. 2934944%=1. 96-(0. 856647509)(1. 96) (100) ForceMass=acceleration 0. 485N0. 261kg=1. 858237548 m/s2 Distance= 12(acceleration)(time in seconds)2 2(Distance)(t)2= acceleration 2(. 8)(0. 93)2= 1. 849924847m/s2 V. terminal There are several errors that could have occurred during this lab.One of them might have been that I could have corrupted my calculations. I am not to entirely sure with how I calculated my percent error and therefore I might have a lower percent error notwithstanding I would not even jazz it or vise versa. A way to correct this problem for the future is by asking for more(prenominal) assistance from others in the class. I am more than sure that others who grasp the concept easier than me would be more than willing to aid me. Another error that could have occurred was that of miss reading the scales for the force in the second lab.Although important to read the scales as accurately and as quickly as possible, one could only do so much. There was only less than a hang-up second to read the correct or desired reading from the scale. One way to correct this error in the future is to have a larger group work on the same lab. Therefore all the students in the group could work together to find out a solution as a team rather than an individual effort. The group would learn better as a result because there would be hands to complete the work and more brains to understand that work that is being recorded.All thought the margin of error was higher(prenominal) for this lab, it is understandable because it was nearly impossible to record the force of Newtons desired in the split seconds one had. With all the information above, it is pee that there is a tie between Newtons Third Law and his Second Law. It is possible to understand that Newtons Second Law deals with changes in state of motion while Newtons Third Law deals with the relation between forces On my honor, I have neither given nor received unauthorised aid on this assignment.
