4. Change the spring length, and do 3 trials. Experiment2: 1. change the height of the car, measure the height between car and photo gate, and record the time of the car go through photo gate, and do 3 trials. DATA: Experiment1 | Distance Stretched (m) | Time(s) | Velocity (m/s) | EPE (J) | KE (J) | Percent Error (%) | Trial 1 | 0.175 | 0.104 | 0.959 | 0.100 | 0.092 | -8.083 | Trial 2 | 0.135 | 0.135 | 0.743 | 0.060 | 0.055 | -7.382 | Trial 3 | 0.115 | 0.154 | 0.649 | 0.043 | 0…
Miami Dade College – Wolfson Campus PHY2048L – General Physics Lad 1 Error Analysis Group: Max Bentata, Corina Pollini, Maria Saavedra 1/29/2015 Introduction: The error analysis experiment was to determine the acceleration of a free fall object. This experiment is also to become acquainted with types of error and statistical methods for analyzing one's data and for estimating its accuracy. It is also to determine how close is the value of acceleration to the accepted value (9.81m/s/s) when…
Pre-Lab Report The objective of this experiment is to learn which scientific glassware should be used in various circumstances, how to measure volume and mass and how to record laboratory data and observations. Become familiar with significant figures, errors, precision and accuracy associated with the various tools and techniques. To Contain Glassware you will need two Erlenemeyer Flasks, one 125 mL to measure 100 mL and one 250 mL to measure 150 mL. You will also need one 100 mL beaker to measure 50…
least five different cart weight trials, starting with being the hanger plus 10 g, and being the cart with no additional weights. In part three, keep the system mass constant but change the force pulling the cart by transferring mass from the cart to the hanger for each trial. Start with the setup the same as your last trial for Part II: 40 g on the cart and 10 g on the hanger. Perform five trials and again take care to make good records of the mass for each trial. In part four, keep the cart mass…
volumetric glassware should be clean and dry before used. The volumetric glassware, measuring cylinder and pipette should be handled with care and all the precautions were be taken during the experiment was held. This was to ensure to avoid any errors such as parallax error especially while reading water meniscus. This experiment must be repeated three times or more and take the average reading to get more…
experiment was to determine the difference (if any) between sorting a standard deck of cards and a low vision deck. Three tests: color, suit, and number sorting were compared. The dependent variables in the experiment included time and the number of trials it took for the student to complete the task successfully. The independent variables were sorting the two different decks by color, suit, and number. Hypothesis: 1. There will be a significant time difference between sorting the standard…
density of water using the experimental data and to calculate the % error by comparing it with the standard density of water at the same temperature. This data will then be used to figure out the accuracy and precision of this experimental procedure. Another purpose is to write a technical write up for a chemistry lab experiment. Data Chart 1: Determining the density of water-100 ml graduated cylinder Trial 1 Trial 2 Trial 3 Mass of 100 ml grad cylinder + water 104.03 g 123.90 g 74.30…
Of course the best choice is the one that is most likely to work, however if it fails trial and error takes over. Doing the problem is the act of applying the solution to see if the problem is solved. Finally evaluating the results is the act of looking back to see it the problem has been solved or the desired effect has been reached. Sometimes…
Running head: INVESTIGATING THE EFFECT OF TASK SWITCHING AND TASK REPEAT ON REACTION TIME AND ERROR RATES Does Task Switching and Task Repeat effect reaction time and error rates? [ANDREA FONVILLE] Brooklyn College - CUNY Summer 2015 Abstract Increasing levels of stimuli in today’s society make multi-tasking a consistent reality. Task Switching (Monsell, 2003) proposes that reaction time will slow when people have top switch between different tasks. Performance is faster and accuracy is…
