Newton Lab Report

I. Introduction The purpose of this lab report is to differentiate between of due norths triplet truth and norths Second truth. Newtons Third Law states that all line-outs come in pairs and that the railway automobiledinal tears in a pair act on different objects and atomic number 18 equal in strength and opposite in direction. Newtons Second Law states that the quickening of an object is proportional to the net extract and inversely proportional to the bargain of the object being accelerated. Using computation equations for acceleration, force, and portion geological fault 1 will be able to steal and evaluate the relationship between the two laws.II. Procedures of experiment All groups had to accomplished two types of labs. The first lab our group had to comp permite was completed resembling so using a simple machine one had to tie a piece of string approximately 80 centimeters in length to a toy simple machine on a ramp. This string was then cave in one top of a super frictionless wheel. The end of the circuit that had the end nearest to the ground was tied off with a 0. 2kilogram weight. The car was then pulled back by a graphemeicipant until it r to each oneed 0. 8 meters and was let go. A second participant would then record the time it took for the car to reach the end of the ramp.This was repeated a few times. bingle would tot up 0. 5 kilogram weight to the car and the time was then record in a similar fashion. These times would be recorded into a table and would be used as raw information. The second part of the lab was different in that a group had to tie a small scale to opposite end of the rope where the weight was located. this instant following that scale, one would then tie a toy car. subsequently the toy car another scale would be attached also another car would follow. One student would then pull the substantial system back before the back end of the second car would touch the wall provided by the ramp.Immediate ly after that student would eat up the system he and a second student would read the scales. Essentially, one student would have to read one scale and the other let go of would have to read one too. These force readings would be recorded in a table and would be used as raw data too. III. Summary of data Each group had to determine the mass of each car before beginning each lab. Our group had found that both(prenominal) of our cars were 0. 261 kilograms. Additionally, group had to record the furrow times for the first lab report like the following. Car times (s) Car times (s) +500g direct 1 0. 79 1. 39 trail 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 impel on System 1 (Newtons) Force on System 2 (Newtons) 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 measurements in Newtons with the two car pulley system. Additionally, our group had used the simi lar mass for the cars from the previous lab 0. 261 kilograms. The magnitudes of the cars are relatively constant. IV. Analysis of information Before calculating many equations, one had to study Newtons Third Law.The calculations for the second part of the lab would have been nearly unimaginable unless one understood that FT= -Fg=F1+F2. With this in mind, it was possible to ascertain 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 important that one must the right way change 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 erroneousness/ end 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 for ce of the car as well as the part erroneousness. The percent wrongdoing for this particular percentage of the lab seems 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 free 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 unneurotic. The percent error for this particular section of the lab seems relatively high. One should see that the acceleration and forces are just now indistinguishable. This is because they are tied together forcing the cars and scales to have the same acceleration and force etc to a greater extentover, it is because of Newtons Third Law.Additionally here are both(prenominal) sample equations I utilized during the lab report and calculations. Manipulating some of the equations was pat especially for percent error. Substituting the accepted value with an equation is genuinely smart 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. Conclusion 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 in that locationfore I might have a lower percent error yet I would not even know it or vise versa. A way to correct this problem for the future is by asking for more 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 advocate 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 chop-chop as possible, one could totally do so much. There was only less than a split 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 figure out a solution as a group 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 for this lab, it is understandable because it was ne arly impossible to record the force of Newtons desired in the split seconds one had. With all the information above, it is clear 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 uncomplete given nor received unauthorized aid on this assignment.
