Drag-and-drop

(The Physics Classroom, 2015). The faster an object travels the more air resistance. As the object moves faster, the object will have to push the air molecules out of the way, which in turn, creates drag. Also, if the object has a large cross-sectional area, the object will experience more drag for the reason that the air molecules must travel farther off the object (SEED, 2015). Crumple zones are the areas of a vehicle that are designed to absorb impact during a collision in an intended…

strategic placement of indentations maximizes lift while minimizing drag, thus leading to the modern day design of a golf ball. Drag and Lift In order to determine why golf balls have dimples, it is important to first look at the forces in the system as a whole. When a golfer hits a ball with a club, it soars through…

the components of an airplane side by side or abreast in a supersonic stream unless there are compelling reasons for such an arrangement.“ 2.1.1 Wave Drag This type of drag is formed as a result of shock waves formed around an aircraft. Wave drag is the main reason behind the designing of oblique wings. This design has been found to reduce wave drag for a supersonic aircraft and can be believed as an aerodynamic evolution to swept wings on symmetric aircraft configurations. This wing is not…

Determining the effect of the mass on the drop time of a parachute Introduction and hypothesis The drop time of a parachute is dependent on multiple factors. Apart from mass, there is the obvious height, area of the parachute and other external factors such as wind. Mass is one of the main effectors of the drop time of a parachute, which can be proven through Newton’s second law, F=ma (Force=mass*acceleration). Rearranged, this gives a=F/m, where acceleration can also be gravity, if falling down…

and combination reels. The reel weighs about ten pounds compared to a reel that weighed 2-3 back when fishing first started. An offshore reel can fit sometimes up to 1000 yards of line onto it. Offshore reels are also now equipped with a very heavy drag system, which means it can take more resistance. If a shark was on an onshore reel, it would nearly be impossible to reel in because the shark would take more line than you have. Even though many fishermen have switched to specific rod and…

optimised. While there are several alternatives that can be used to do this, simulation stands out as one of the better ones. Computer simulation is intuitive; it allows the modeler to keep visual track of the created objects and processes. Use of drag and drop tools during the creation of simulation models also simplifies the process, allowing those with minimal programing experience to work with the tool. Finally, calculations of key indicators are automatically performed within the…

Candy Land is a brand new, hydraulic steel roller coaster ride, using an abundant amount of modern technology, recently added to Hershey Park. Loops, a corkscrew around some delicious ice cream, and a 100 foot drop are all included in the ride. Not only is there scrumptious looking scenery, but also the roller coaster has an average speed of 60 miles per hour, and can reach speeds up to 85 miles per hour. If friction and gravity were not present during the ride all of the passengers would go…

The purpose of experiment six was to better understand how to measure and read volumetric flow rate of water through a pump, and to better understand how flow meters work. In this experiment, the relationship of the plot between the orifice and Venturi meter pressure differential showed many correlation with each other. The volumetric flow rate had a square root relationship with the previous stated pressure differentials. The error in this lab was also extremely low appearing at around…

Interface Design [Add usage scenario] 1. PocketMenu (Adapted from Pielot et al.’s paper, 2012, CHI) [Do I need to describe the original work first, and distinguish the difference? Or should I depict my adapted design directly?] Adapted from Pielot et al.’s work, PocketMenu, this design aims for providing a new type of menu interaction without the needing of visual feedback. The menu item stack is located along the bottom left edge of the screen vertically. Its precise location depends on the…

materials, steel, wood, and fiberglass. It opened on April 1st, 2006. The Goliath’s top speed is 70 MPH, the height of the first is 200 feet with a drop of 170 feet following it. The duration of the ride is 3 minutes 30 seconds. The coaster can harbor 26 riders per vehicle. The main feature of the Goliath is the 20 stories the riders go up and drops them at 4,480 feet of track at speeds up to 70 MPH. Roller coasters exhibit many different types of potential and kinetic energy. The law of…
