• ## Bird Flight Lab Report

surface area is included in the formula to find the drag against an object. So as area increases, drag increase. Shape: Affects the Drag coefficient in the equation, some values include: Shape/Object Drag Coefficient Bird 0.4 Dolphin 0.0036 Sphere 0.5 Bus 0.6-0.8 Thin Disk 1.1 Speed: Similar to surface it is also included in the equation and is directly proportional to Drag force. Fluid Density: Increased density means an increase in mass, which increases resistance to the object that is…

• ## Piezo Effect Essay

The history of piezoelectricity evolution is over 120 years which was discovered by brothers Curie in 1880. They were Pierre Curie (1859-1906) and Jacques Curie (1855-1941). During the study of the generation surface electrical charge by applying pressure on some material, they found out an unusual phenomenon which was a voltage of opposite polarity was generated by pressure was applied on the crystalline minerals such as quartz. The amplitude of the generated voltage was proportional to the…

• ## Newton's Second Law Lab Report

an air-cushioned track was set-up for the glider to ride on a pocket of air without being in contact with the metal track. In addition, this glider will have masses attached to it as well as a hanger which will act as part of the same system. The masses in this system will be exchanged between the glider and the hanger. In this case it will stimulate an added force by interchanging the masses; as a result increasing the acceleration. Moreover,…

• ## Thermometric Error Analysis

thermocouple is modeled as shown above by discussion leading to Equation 5.3. Thermocouple attached to the surface of a massive solid whose temperature we would like to measure. Excepting where the thermocouple has been attached the rest of the surface of the solid is assumed to be perfectly insulated. Since the thermocouple conducts away some heat from the solid there is a depression of temperature of the solid where the thermocouple…
