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…

dropped I probably got the wrong height of the balls bounce. Bounce meaning the quality of a substance that is able to rebound. When you throw a ball on the ground it bounces right back up to you because when the ball hits the ground it puts an equal force back on the ball. Balls are made out of a rubbery elastic material, meaning they can…

of air resistance acting on you due to friction and your direction. During this part, you experience high G-forces acting on you due to your position. Once you are down the mountain, you are lifted towards a loop. In this loop, you are experiencing a centripetal force, or the force an object moving along a circular path to move toward the center of the path. You experience a large g-force in this loop due to your position upside down. When nearing the end of the loop, you experience projectile…

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…

The aftermath required that drivers wear neck and head restraints. Helmets were further improved and safety precautionary became key concerns. NASCAR also joined forces with Indy Car and the team from the University of Nebraska-Lincoln. The results of their merging introduced the Steel and Foam Energy Reducing systems known as the SAFER barrier. The barrier is basically a stack of eight inch by eight inch steel tubes, cabled and bolted to a solid wall with foam pillars cushioned between them. In…

both internal and external forces. Internal forces occur within the bridge, through tension, compression, bending, etc. External forces are applied to the outside of the bridge, and can be static or dynamic. The static load of the bridge is the bridge itself, and the weight of its members and components. This is created by the force of gravity pulling on the members of the bridge. The dynamic load moves and changes, such as traffic, people, wind. It is created by the force of gravity on an…

variables involved like air pressure, rotation of the ball, and aerodynamics. These are very important factors when a baseball is thrown. A Big part of velocity is the air pressure, this is because of a separate topic called the Magnus Effect - a force exerted on a rapidly spinning cylinder or sphere moving through air in a direction at an angle to the axis of spin. This is what I am testing in this experiment using the average velocity formula v=(Df-Di)/t. I will test the change between the…
