CO2 Dragster Design Study Guide Force- is a push or pull when energy is applied to an object. Friction- is another enemy of acceleration and speed. Rolling friction- occurs when one surface roles over another. Sliding friction- occurs when one surface slides over another. Fluid friction- occurs when an object moves through a fluid, such as air or water. Drag- is the force of air on a moving object; it has 2 components; what are they? Frontal pressure and Rear Suction Aerodynamics- the study of how solid objects displace fluid air and other gases. Wind Tunnel- is the machine that calculates the drag of our dragsters. Newton’s First Law of Motion- Inertia Law- a property of matter by which it remains at rest or in uniform motion unless that state is changed by some external force. Newton’s Second Law of Motion- also known as f= ma. Thus, heavier objects require more effort to move at the same speed or distance as a lighter object. Newton’s Third Law of Motion- states that for every action (or force) there is an equal reaction (or opposing force) in the opposite direction. Engineering Design Process- linear process by which we constructed our dragster. Specifications- are a given set of rules or limits you used to design your dragster. What elements stand out when talking about designing a successful dragster? Weight, Friction (Fluid, Rolling), Specifications, Appearance Advertising Vocabulary Target audience- objective; who the product is aimed at. Product Placement- playing a movie or tv show to prominently display a company's product during the film or show. Jingle- catchy tune usually rhyming, simple, and repetitious used to promote a product. Slogan (Tag Line)- phrase used to advertise a product, or to identify a company or organization. Logo- a sign or symbol in shorthand, it is a particular form of symbol which presents in a graphic way a word or group of words. Propaganda- the deliberate, systematic attempt to shape perceptions, manipulates cognitions, and direct behavior to achieve a response that furthers the desired intent. Types of Propaganda Bandwagon- Tries to persuade everyone to join and do the same thing. Loaded Words- Using words with strong emotional associations. Plain Folks- Suggesting something is practical and a good value for ordinary people. Glittering Generality- Using words so strongly positive in emotional content that just hearing them makes you feel good. The words express a positive meaning without actually giving a guarantee. Transfer- Transferring good looks, feelings, or ideas to the person who the propaganda is meant to influence. Suggests the positive qualities to be associated with the product and the user. Testimonial- Using a famous person to endorse the product. Repetition- Using the product name or a keyword or phrase over and over.
