By finding the area underneath the velocity versus time graph and by adding up all the displacement intervals gave values near each other. This means that there are 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…

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…

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…

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…

An Experiment on a Bird in the Air Pump is a painting by Joseph Wright of Derby (An Experiment on a Bird in the Air Pump). Painted in 1768, oil paint on canvas, it serves to express the Industrial Revolution (An Experiment on a Bird in the Air Pump). The painting’s dimensions are 183 centimeters tall and 244 centimeters wide (An Experiment on a Bird in the Air Pump). This paper’s purpose will be to analyze and interpret not only Wright’s art, but his life and era as well in an effort to…

The Poi Pounder Poi pounders are a powerful tool used in my Hawaiian culture . Poi pounders start off as an ordinary rock, like how I was born at birth. An ordinary child , The pedestal which is the bottom of the pounder , represents what holds me and my knowledge. The core represents how my family shaped me into the person I am today , and the top represents my religion. Starting from the bottom of the poi pounder , the pedestal represents my knowledge and what holds me . In my culture we…

Stress is a state of well-being when an individual feels strain due to demanding or adverse circumstances. Stress can factor in our lives in a various amount of ways in the form of daily hassles, major life events, conflict, and frustration. Those are not the only things that affect a person's well-being, having a mental health issue can also be negatively emotionally and physically taxing on an individual's physical and mental well-being. About 44% of Americans feel more stressed than they did…

I don’t know why? But when people start growing up or start getting older they start slowing down in their triathlon performances. Not long ago, I saw an old man in great shape doing a triathlon and something caught my eye because he had been a word champion in the ironman competition; but although he was very slow in the competition that I saw him in. later that same day I got home and started researching his name online and I found some of the races that he had done with the times and he was…

Stress is a normal physical response to events that make you feel threatened or upset your balance in some way. (Melinda Smith, M.A., Robert Segal, M.A., and Jeanne Segal, Ph.D., 2014). We experience stress on a daily basis, but what may be stressful for some, may not be so for others. Stress can be caused by, working long hours or under dangerous conditions, having to give a presentation in front of classmates or colleagues, getting divorce or having financial problems, all of these examples…
