Essay On Centripetal Force

Evaluation
Conclusion Statement:
Centripetal force is inversely proportional to radius and therefore centripetal force is decreasing exponentially as radius increases. This can be supported by my equation of Y=A/x +/- .05 where A= 0.3322
The graph of my data collected showed my predictions were incorrect, I thought that the larger the radius meant the larger centripetal force would be shown, however it was actually inversely proportional. The experiment concludes that centripetal force will decrease as the radius increases.
The graphs for minimum and maximum lines had uncertainty percentages lower than 3%, it was 2.49% which means it’s small but not too small. With this being known, I have found that my experiment has low random error. This means that the experiment was highly accurate and the data could be reproducible. With no outliers, it makes sense for this to be the uncertainty. This conclusion makes sense because of my data in the graph, viewers can clearly see the inverse relationship between the two variables.
Conclusion and Accepted Theory
Seeing as all of my data for the slope and y-intercept fit in the range expected there is little to no systematic error. My error bars were all

Another project I could do to research centripetal force is the Spinning Penny experiment. The force in action in that experiment involves centripetal force. Since it’s the force that is always directed toward the center of circular movement and is actually responsible for keeping the penny moving in a circle. I could relate this to the inside the balloon, it’s the wall of the balloon that causes this to happen. Out in the solar system, it’s the pull of the Sun’s gravity that keeps Earth in its circular orbital

    I accumulated my three results added together, dividing it by three and with that I divided Force friction over Force pull and received an average (Mu) of .63 for sandpaper. My partners accumulated their results and received a .34 for the average (Mu) of cardboard, .63 for cork and I did rubber which gave me the average (Mu) of .65. When solving for the percent error, I was universally and mathematically off the charts in terms of a number scale when I solved for the percentage. For example, I reached 140% as my percent error for sandpaper which would definitely be incorrect. I messed up the number scale in my trial when reading off the spring scale, thus causing my calculations and data to be…

    Bottle Rocket Experiment

    Discussion It can be seen from the experimental data, that the relationship between the difference in initial pressure inside the bottle rocket and the atmosphere, and the vertical height reached by the bottle rocket after 0.1 seconds, is proportional. This is quantitatively demonstrated by the high R2 value of 0.99533 of the graphed relationship, which indicates the likeness of points in a data set to an established trend; where 1 = a perfect relationship. The gradient of 0.0236 in the best fit regression line of the data, indicates that for every increase of 1 PSI in pressure inside the rocket, 0.0236 more vertical meters were travelled by the rocket in the first 0.1 seconds of its motion. This is only approximately 30% of the distance per PSI increase value of the predicted function in the hypothesis, which postulated that 0.0792m more would be covered in the first 0.1 seconds of motion per increase of 1 PSI.…

    Over the course of the roller coaster height lab My group and I had to answer the question “ does the height of the ramp affect the speed of the marble”. We answered that yes the height of the ramp will make the speed of the marble increase. Our hypothesis was wrong, but, My group and I have discovered that the height of the ramp will not affect the speed of the marble. We also Discovered something new which was that the speed increased and decreased abnormally as we went along in the lab.…

    The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. It also helps when determine which isomers predominate. The experimental melting point of the E-stilbene was 242 degrees Celsius. The actual melting point of the E-stilbene was 241 degrees Celsius. This verifies that the predominating isomer is meso indicating that the cyclic intermediate remained.…

    Carpi and Egger’s reading “Uncertainty, Error, and Confidence” discusses how there will always be a small portion of error in all scientist’s works. However, there are two different types of error: statistical and systematic and the main difference between the two is that statistical error is random and systematic error can be compensated for during an experiment. Scientists do not report just a single value as a measurement due to these types of errors in experiments, they report a certain range of values, which is a confidence interval. Another key aspect within the reading is in regards to uncertainty. Scientists must accept and realize that there will be errors within the measurements, thus a sense of uncertainty.…

    Paper Bullets Experiment: Data Analysis The scientific question that was investigated by the paper bullets experiment asked, “Does the width of a paper bullet affect the distance it travels when it is launched?” The hypothesis that goes along with that question is, “If a paper bullet has a larger width, then it will travel a shorter distance than a standard paper bullet with a width of 4cm.” Variables in this experiment included independent variable (width of the starting piece of paper used to make a paper bullet), dependent variable (the distance that the paper bullet travels when launched), and the control variables (size/type of rubber band, device used to launch paper bullets, area used to conduct experiment, paper used to make paper…

    I believe that the Eikmeier Center of Gravity (COG) Methodology, is the best method of identifying a COG for three reasons: It is testable, it defines the COG at the strategic and operational level, and it has a more comprehensive analytical approach. Firstly, the Eikmeier and Godzilla methodologies are testable, but the Critical Factor Analysis (CFA) isn’t. The CFA is already at a disadvantage down at the tactical level because testability is a crucial piece of intelligence that validates the criticality and feasibility of a given Course of Action (COA) developed during the planning process. Testability of the COG is a central element that allows the commander to focus his efforts on developing a COA that maximizes the desired effects on the enemy, minimizes the use of redundant or useless resources and sets the conditions for follow-on operations. Validation of a COA enables commanders to request, coordinate, and synchronize warfighting functions so as to seize the initiative, retain the gains and exploit the situation to maintain a position of relative advantage over the enemy.…

    ASTROPHYSICS Methods used to search for extrasolar planets Lucky Ruangsiri 24.02.2016 Extrasolar planets are planets that revolves another star apart from our solar system. The human race has found nearly 2000 confirmed extrasolar planets by the year 2016, and this has fuelled the search for extra-terrestrial life as we scour the universe for anything out there. How do we discover these planets that are light years away from the earth? An extrasolar planet detection technique is the Doppler technique, also known as the wobble method or the radial-velocity method.…

    The effective permittivity from equation 1, calculated from the experiment was Ɛeff =3.31, the class average was Ɛeff =3.31, and the literature value was Ɛeff =3.28. The class average is the same as my value due to the measurements calculated for the effective permittivity were close and did not have an number that was wrong and was due to error. The literature value shows that the value found in the lab has error in involved, but is accurate enough to be considered. The Loaded Quality (Q) Factor from equation 2, calculated from the experiment was QL= 45.51and the class average was QL= 41.2. It seems the percent error of the class average versus my value was 10.43 %.…

    NEWTON’S LAWS OF MOTION Water rockets have used many times to test and explore the fundamental principles of physics. To understand what determines how far a water rocket may fly or how a rocket may even lift off, it is important to delve into the deeper detail; the forces acting in play. Newtons Laws govern the central principles regarding the physical forces which may act on a particular object in space. There are three laws which were developed by Sir Isaac Newton in 1686, when he published his book Principia Mathematica Philosophiae Naturalis (NASA, 2015).…
