Free Fall - 1058 Words

Sample Formal Laboratory Report for Physics on the Picket Fence Lab (CP) without the parachute Purpose: The purpose of this experiment is to verify the acceleration due to gravity using the picket fence with a photogate, LabPro and LoggerPro software by measuring it with a precision of 0.5% or better. Theory: All objects, regardless of mass, fall with the same acceleration due to gravity assuming that there is no air resistance. Objects thrown upward or downward and those released from rest are falling freely once they are released. Any freely falling object experiences acceleration directed downward, regardless of the direction of its motion at any instant. The symbol â€Å"g† is used for this special acceleration at the Earth’s†¦show more content†¦Having the fence short keeps that error minimal. A reading such as part 1 trial 3 (9.87) which is above the actual value of g indicates there may have been a minor problems with this drop. Proper dropping technique will minimize many errors associated with this lab. An automated dropping device would significantly improve the precision of this lab. Equipment measurement precision does not have much affect on error because the computer can record to many decimal places—depending on how it gets set by the user. Ultimately, the laboratory was partially successful in verifying the acceleration due to gravity given the low percent difference (error) to the accepted value, however the objective to measure g to a precision of 0.5% was not achieved. When trial 3 is removed and the precision is recalculated, the objective is achieved. Based on this, the experiment results could be improved by performing the experiment again with an improved method for dropping the picket fence. -----------------------Show MoreRelatedFree Will and Fate: Things Fall Apart844 Words   |  4 PagesFate and Free Will The idea about free will and fate is still unsolved and debatable throughout the world. Some claim that humans have their own power to create their own destiny, however, others argue that they are inescapable victims of fate. The novel, Things Fall Apart, portrays the relationship between human’s determination to succeed and his or her own fate by describing Okonkwo as a tragic figure.

(Freeman, Jo) But there were many events leading up to this point. The Free Speech Movement began to obtain momentum in the fall of 1963 and the spring of 1964 the Bay Area was rocked with the civil rights demonstrations against employers who practiced racial discrimination. (Freeman, Jo) These students believed that this was wrong and felt the need to do something about it. So many BerkeleyRead MoreEssay on Free Fall Lab596 Words   |  3 PagesFree-Fall Lab Assignment Nishad Gothoskar Physics Online Experimental Design: In order to design an experiment to measure free-fall acceleration, the researcher must construct a wooden tower with height 10 meters along with a trap door system to release a tennis ball from rest position. In this case, the researcher must measure the time the ball takes to free-fall from rest position to the ground. Using this info and the formula: s=vit+ 12at2 s = 10 m vi = 0 m/s The researcher willRead MoreFalls Prevention Within The Older Adult Over The Age Of 55 And New And Alternative Interventions For Fall Prevention1066 Words   |  5 Pagespaper will discuss falls prevention in the older adult over the age of 55 and new and alternative interventions for fall prevention compared to current practice. The desired outcome of the paper is to provide information for fall prevention and, therefore, decrease the occurrence of falls. First, in order to understand the importance falls have within the clinical setting, statistics showing the mortality, morbidity and financial impact should be understood. The occurrence of falls within the acuteRead MoreAdvanced Professional Roles and Values Wgu4119 Words   |  17 PagesAdvance Professional Roles and Values Project Falls Keri Cochran October 20, 2014 Western Governor’s University The problem and explanation: The hospital I am employed at is currently having an issues with patient falls.

Milton enables these characters to make their own choices and have their own consequences based on their own decisions and free will. Throughout the poem, John Milton supp orts this concept of
