In this course, we will engage in graded discussions that focus on "the real world" by applying the physics concepts we are learning to both everyday life and to aviation. After completing the readings and concept-related activities in this module, you will be prepared to engage in this discussion. Initial Post Instructions and Requirements: 1. Choose a discussion topic that uses physics topics covered in this module. Consider one of the following as good topic "starters" for discussion: (i) What were your "Aha!" moments as you worked through the material? (ii) How does this module's content relate to your professional career? Personal life? (iii) How does this module's content relate to current events? (iv) Did you more deeply explore a topic only covered lightly in the course materials? What did you discover? (v) What concepts (learning objectives) did you struggle with? What resources helped you overcome this hurdle? Do not post homework problems. 2. Create an engaging 3-paragraph initial post that ties one or more of the module's concepts to the real world. The paragraphs should address the following points: Paragraph 1: Describe the physics concepts/topics you have chosen to discuss from this week's module, including, as appropriate, a reference to this week's readings on the topics, terminology with definitions, units, conventions, etc. Paragraph 2: Summarize one or more impacts of the physics concepts to everyday life or aviation. Paragraph 3: Either: (i) provide a real example, e.g., from an article or documented report of the aviation impact of this physics concept, or, (ii) give "your take" on the relevance and importance of this topic from your own perspective, by providing personal points of view or related experiences. Length. Because your initial post will be scored on the degree to which you meet these standards, there is no set minimum word requirement. However, there is a set maximum word requirement - confine your initial post to 500 words. Remember we are all reading each other's posts, and a succinctly written post is more likely to be read and responded to, thus furthering our discussion on that topic. Graphics. Include a graphic, video, or image within your post (do not attach) that helps visualize some aspect of your initial post discussion. To include a YouTube video, simply paste the video URL into your post, or embed the video using the Embed app on the toolbar. To embed images from the web directly into the discussion post, review the Canvas resource, How do I embed an image in a discussion reply as a student? (Canvas Community). >>> If you have trouble embedding the image into your post, you can simply insert the image URL directly into your post. Timing. Post your initial post by the fourth day of the module week. You will not be able to see any posts until you post your initial post. 3. Post substantive responses to at least two of your classmates' posts by midnight Eastern Time on the seventh day of the module week. At least one of the responses must be to a topic you did not choose for your initial post. Each response should add thoughtfully and substantively to the discussion, by covering two or more of the following areas: (i) elaborating with additional factual details; (ii) providing an alternate perspective; (iii) sharing a related experience; or, (iv) asking a related question. Overview In billiards (pool), why does the cue ball sometimes stop completely, and the ball it collided with goes off as fast as the cue ball was originally going? If you actively push against a brick wall all day, have you actually done any work? Conservation of energy Highest point of swing Maximum kinetic energy Maximum potential energy (no kinetic energy) Do police use physics, such as conservation laws, at the scenes of accident investigations? Now that we understand what constitutes a force and how forces apply according to the laws of physics, we'll begin our study of energy and the conservation of energy. We'll start with the theory of linear and angular momentum and how the conservation of momentum is used to solve inelastic collisions. The study of collisions is fundamental to determining what happened during a vehicle accident, whether the collision is between cars and trucks, or aircraft. We'll also look at elastic collisions, but due to the mathematics involved, we only look at what happens in a qualitative sense. We will then develop the concept of work, explore the concepts of potential and kinetic energy, and ultimately understand how the three are related and can be converted from one form to another, especially in a gravitational context. These concepts will be used extensively in succeeding modules. Finally, we will look at some elementary aspects of orbital mechanics, which have an impact on space launches and satellite performance. Module Objectives Upon successful completion of this module, you will be able to: 1. Evaluate how momentum and energy are involved in elastic and inelastic collisions. (LO3) 2. Apply the concept of momentum to elastic and inelastic collisions. (LO2) 3. Solve problems involving the conservation of momentum and/or energy. (LO4) 4. Differentiate between situations where work is and is not done. (LO2) 5. Solve practical problems using the concept of work. (LO4) 6. Apply the concepts of potential and kinetic energy to examples where energy conservation takes place. (LO2) 7. Apply the concept and definition of power to solve problems associated with power. (LO4) 8. Apply the concept of angular momentum and its conservation to practical problems. (LO2) 9. Interpret results of experiments involving energy concepts. (LO5) 10.
