Bow And Arrow Experiment Essay
Introduction: A bow made out of a rectangle cut from an ice cream carton and a piece of string was used to shoot an arrow which was made from a drinking straw with a blob of plasticine on the end. The bow was placed on a lab jack so that the height could be adjusted. Research question: What is the relationship between angle and horizontal displacement . Independent variable: Angle of projection (θ) Dependent variable: Horizontal displacement (S) Controlled variables: Height of the stand (h) Position of bow and arrow on the stand. The distance that the bow is pulled back before shooting. Length, width, mass of arrow and bow. Theory: Assuming that the air resistance has minimal …show more content…
After the arrow landed on the table, its horizontal displacement was measured using a ruler with an uncertainty of ±0.05cm, from the edge of the stand to where the arrow landed. Measurement of horizontal displacement: In measuring the length of the horizontal displacement, a ruler was used which has an uncertainty of ±0.05cm. Ruler was aligned with the center of the protractor. The arrow always landed with the plasticine end first, it sometimes bounced but I carefully watched the landing area and marked the point where the arrow first touched the ground. Measurement of angle: When measuring the angle I used a protractor, which has inaccuracy about 5 degrees. It's a pretty big inaccuracy, but it should not prevent confirmation of the hypothesis. Centre arrows I put at the center of the protractor, as shown at the beginning of the work. The height of the protractor was regulated so that the arrowhead coincides with the central reference point in the protractor. And then with the help of my assistant, who used a different ruler to measure the angle of inclination to be as accurate as possible in our
Summary Of Bruce Feiler's Learning To Bow
1312 Words | 6 PagesIn the book Learning to Bow, written by Bruce Feiler, Feiler is sent to Japan to teach Japanese students about American values, customs, and its language. Feiler discusses his life and teaching experience in Japan during the late 1980’s and early 1990’s.

He is enabled through this immersion to better understand the vast similarities and differences between these two distant countries.

The measures made on the N-S component of the instrument are more reliable than those on the E-W one that was repaired at best by the OGS technical staff after the partial detachment of the moving mirror. The error associated to with the estimate is evaluated as the amplifier error, equal to 1% on the linearity of the response, plus the uncertainty on the voltmeter, equal to 0.05
The Bronze Bow Essay

This book demonstrates that change is a process achieved over time and through experience. For Daniel, many of these experiences challenge his long-held beliefs and cause him to rethink his preconceived perceptions. Readers who contemplate Daniel’s story will find themselves wondering about their own prejudices and perspectives.

2403 Words | 10 PagesThe measured tensions were normalized relative to the maximum tension and the lengths were normalized relative to the length at which maximum force was generated (Ln = 29 mm). The measured data and expected data were plotted together (Figure 3). Correlation between measured and expected tensions at the same normalized lengths was determined for the three expected segments of the length-tension relationship.2,3,4 This was done using piecewise linear regression and yielded r2isometric = 0.956033. The fitted curve for the isotonic experiment resulted in r2isotonic = 0.960557. The F0 was 19.5 N for the fit and 6.35 N for the guess.

692 Words | 3 PagesThen, by holding the nose of the bullet pointing away from you, the direction the impressions run away from you (either to your left or right) determines the direction of twist. If the rifling impression pattern on the bullet matches the rifling pattern in the barrel of the questioned firearm, the next step is to measure the rifling impressions on the bullet. The lands and grooves on a bullet are measured in thousandths of an inch or in millimeters. One way to measure individual rifling impressions is to use a micrometer, or with advanced technology the majority of crime labs use a comparison microscope; which is two microscopes connected to an optical bridge which allows the viewer to observe two objects simultaneously with the same degree of
Deflategate Experiment
476 Words | 2 PagesIn conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.
Mental Rotation Experiment Essay
1939 Words | 8 PagesTitle: Mental Rotation Experiment: The effect of Gender on Mental Rotation Reaction Time Introduction: Mental rotation is an important function of visual representation in the human brain when dealing with misoriented stimuli, which is the ability to rotate two and three-dimensional objects in one’s mind. In everyday life, people’s ability to recognize faces and objects from unconventional perspectives stems from their ability to mentally rotate objects. The earliest experiment to research on the concept of mental rotation was by Shepard and Metzler (1971). In the classic experiment, participants were presented with drawings of pairs of two-dimensional figures and three-dimensional cubes that were asymmetrically assembled.
