Air force

novel Sula, Toni Morrison presents nature as an all controlling force over people in the Bottom by emphasizing the embodiment of nature in powerful characters, by depicting a sense of liberation in death, and by illustrating a lack of agency in the Bottom’s population. Morrison first suggests the pervasiveness of nature in the lives of people in the Bottom by creating parallels between powerful characters in the community and natural forces. With this humanized view of nature’s…

two ways to calculate displacement using a velocity versus time graph. Experimental Uncertanties There were several experimental uncertanties accountered in the accelerated motion lab. Firstly, the presence of air resistance. As the object traveled down the ramp increasing its velocity, air resistance increased which affected the acceleration. Secondly, the affect of friction. The presence of friction affected the motion of the object as it went down the ramp. Lastly, the imperfections of the…

Unit Three: Energy Our universe is made up of matter and energy. Matter is made up of anything that has mass and takes up space where energy allows the ability to do work or have the ability to move or elicit change in matter. In other words, energy is a property of objects which can be transferred to other independent objects or be converted into different forms. It is described as “a system to perform work.” We have two different types of energy; kinetic and potential energy. Kinetic energy is…

The same rules apply, gravity is pushing the marcher down and the ground is pushing back. Same with friction, friction keeps the movement steady and momentum determining how fast and how far the movement will take the marcher. This time there is force. As stated, instead of a lift there is a push of the foot giving more momentum to the movement. This can make the marcher go farther or faster but it does depend on how much push you give. You will receive an equal and opposite push back from the…

The force of gravity is a force which means that any work done by it does not change the mechanical energy of the carts. The normal force of the track pushing up on the cars is an external…

4.1 Strength of Anisotropy “The strength of anisotropy is calculated by the “kern and Richter” formula which gives the magnitude anisotropy k= (Vmax –V min)/Vmean, where Vmax and Vmin are maximum and minimum velocity. For P wave in the olivine crystal Vmax and Vmax are 9.89 and 7.72km/s respectively, so strength of anisotropy is 25%. For S wave k= 22% for Vmax and Vmin are 5.53 and 4.42 km/s respectively” [Seth stein 2003]. This anisotropy is the intrinsic anisotropy of the material defined as…

One of the most important activities of science is measurement. Measurement is a means of quantifying properties for identification. For example, density is the relationship between the mass and volume of a pure substance. One could determine if a piece of yellow metal is gold by determining its density. Measurement allows scientists to make comparisons. Measurement also provides a means by which scientists can judge the reproducibility of an experimental procedure. However, measurement is not…

Welcome to the Loop-Dy-Loop!!! This roller coaster is found in the beautiful area of Hersheypark inside the water park. The roller coaster, is filled with many twists, turns, and loops. This roller coaster is not just any roller coaster, it has a fabulous view of the whole park. The tallest point on this ride, where you feel the highest potential energy, is over 4,586 feet tall. This ride is over four football fields long!! While you are waiting in line you can see that the cars have three rows…

supporting our second hypothesis. However, we noticed that there were still minor amounts of kinetic energy lost during the elastic collisions. This is most likely due to friction, because the track provided does not completely remove the friction force. There could also have been some calculation and averaging errors when using the Labquest2 computer system, which would lead to that inaccurate…

In this lab, we observed gravitational acceleration of an object. The tools and materials included a metal track, the car for the track, a piece of index card, a pasco glx device with a photogate sensor, and an object to elevate the ramp. First, the lab group arranged the materials for the experiment. We elevated the ramp up a small angle. The Lab determined the total distance the car must travel to the photogate was 30 centimeters. We then measured a small “flag” that was made from an index…
