View the Interactive titled “Lift and Drag” located at http://www.pbs.org/wgbh/nova/space/lift-drag.html. Be prepared to discuss.
Read the question and answer titled “Why don’t I fall out when a roller coaster goes upside down?” located at http://www.loc.gov/rr/scitech/mysteries/rollercoaster.html. Be prepared to discuss.
Note: Online students, please select one (1) of the four (4) subjects to discuss.
From the first e-Activity, describe how both Newton’s Third Law of Motion and the Bernoulli Effect can explain the generation of a lifting force when air passes over an airfoil.
From the first e-Activity, assess each of the four (4) main types of airfoils for function and purpose. Note: Be sure to include how each impacts lift and drag, as well as what type of aircraft is best suited for each. Provide two (2) other practical uses for airfoils.
From the second e-Activity, imagine that you are trying to convince your apprehensive friend John to take his first roller-coaster ride. Explain to John how the roller-coaster engineers use physics to create a safe, yet thrilling ride. Note: In your explanation, be sure to include a discussion of potential energy, kinetic energy, angular momentum, frictional forces, and inertia when analyzing all aspects of the roller-coaster ride.
Provide two (2) examples of how you either use or are impacted by the principles of potential, kinetic, or mechanical energy in your daily life.
