Background Knowledge The question for this experiment is, Does the angle of an airplane wing affect the average rate of descent of the plane while gliding? So, the thing that is being tested is if the angle of an airplane wing, which determines the average rate of descent. In this experiment, the average rate of descent will be found by dividing the distance the plane traveled by the time it took the plane to land. First, how planes fly needs to be understood. Airplanes fly because the wings…

Paintball Vs. Airsoft There are very few situations where you have to worry about being shot. The one most would think of would be in the field of combat in a different country. Most people don’t realize though that they can get the same adrenaline rush in a safe environment. There are actually two popular ways; Airsoft and paintball. Paintball and Airsoft are both ways to simulate the feelings of live combat and have similar features. In order to begin feeling the adrenaline rush flow…

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…

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…
