Nt1310 Unit 3 Lab Report Error
Our lab results on all three data table experiments had a percent error less than 5 percent. When examining these results I can be almost certain it was not systematic error due to the fact that a major percent error was not detected on every trial that was run in each of the three tables. With there being some percent error there is the possibility for random error which are from unknown factors, which could come from impact of outside forces like the air track interfering with the acceleration of the cart. Beings that this was the first lab for my lab partners and I were working there was room for slight personal errors with our use of the computer program as well as the lab equipment. How does the acceleration in Data Table 2 compare with that of Data Table 1? Why do we observe this difference? In data table 1 the rate of a_calculated was 2.829 m/s2 and table 2 was 4.77m/s2. The acceleration in the first table would be less than table two due to the fact that less mass is added to the hanger. This in turn does not add a greater gravitational pull downward due to the greater level of mass. Which means that the string has added tension, which pulls the cart faster in table number 2. How does the acceleration in Data Table 3 compare with that of Data Table 1? Why do we observe this difference? In data table 3 the rate of …show more content…
This was then tested against adding more weight in the second table, which increased the acceleration due to gravity, which made the second table faster than the third. While the third table went the slowest, because of the added weight on the cart which pulls back against the weight end more than tables on and two. This whole process in finding a_calculated would be the same as finding F=ma. Which makes this lab fully about testing Newton’s 2nd law and then checking out findings with percent

The figures intimate the fault injected FFT,which is checked by the manual error injected via all diferent possibilities by using RTL scripting. Eventhough the soft error is added in the FFT the error detector code 100% detect the errors and corrector correct the errors.

Motor Spin Experiment Report
505 Words | 3 PagesDoes the type of battery used to create a motor affect the time the motor spins? If the type of battery affects the amount of time the coil spins then the D-battery powered electric motor will spin for the longest period of time. The procedures were to create the motor and find a spot for the motor to spin. You also needed to keep track of the time the motor spinned. When the motor stops spinning record the time on a data table.

The numbered steel refers to the ASTM grain-size number. Formula 1 is used to solve for the grain size. n=2^(G-1) Equation (1) at 100x magnification Crystal structures change shapes which changes the strength of the material and its properties. The metal might become soft, brittle, hard, or ductile.

Brainstorm Clock Experiment
883 Words | 4 PagesOn Tuesday in lab, we were first asked to brainstorm ideas for clocks. Some of the things we thought of that could be used as a clock were a simple pendulum, sun dial, your pulse, and drips from a leaky faucet. Then, we spent the rest of our time testing out the drippy faucet idea by poking a hole in the bottom of a cup, placing it above a graduated cylinder, filling it with water, and timing how long it took for the drips to fill up 10mL. While the hole was dripping out water, we had to continually put more water in the cup so that the pressure was consistent throughout the entire experiment. If we did not do this, the water could drip faster or slower depending on how much water was in the cup. We tested the amount of time it took to get
How Did Newton's Laws Of Gravity Effects An Object?
620 Words | 3 PagesHave you ever wondered how the laws of gravity effects an object? This is a question that many people may have pondered, because nothing really explains in detail about it other than elementary explanations. I like to do science experiments in school and I also enjoy history, mainly militaristic, and this is a topic that interests me to try to solve it with experimentation. I believe that learning more about Newton’s Laws of Gravity and Motion may help to explain why a trebuchets counterweight and projectile weight are directly related to the distance fired by the trebuchet.

This theoretical force has a remarkable similarity to gravitation. “Gravitation Concept” will assume that we have finally found the source of gravitation. If “Gravitation Concept” can be established, then the “pressurewarp” cause of gravitation will finally be understood.
Physics Lab: Gravity Demos
1193 Words | 5 PagesIntroduction In the lab “Gravity Demos,” the common objective is to learn more about gravity and the center of gravity by performing various experiments. The definition of gravity is an attraction between any objects that have mass. Every planet has a gravitational pull, for example, earth’s gravitational pull is 9.8 meters over seconds squared (9.8 m/s2). This means that a bowling ball and a feather would fall at the same speed and hit the ground at the same time if there wasn’t air resistance (a force that slows down objects that move through the air.)
