Q This assignment supports the following Unit Objectives: • (U45) Explain that motion in two dimensions consists of independent motions in two perpendicular directions. (CLO4) • (U46) Apply the principles of UCM to predict circular motion. (CLO2)(CLO4) • (U47) Describe qualitatively the position, velocity, and acceleration of UCM. (CLO4) • (U48) Calculate speed, and acceleration for an object in circular motion (CLO2) • (U49) Recognize and use proper units for and object in UCM (CLO2)(CLO4) • (UDS) Develop a well thought out and correct response to various discussion questions (CLO2)(CLO4)(Goal 4) Do not start a new thread. Simply reply to my posting. Be sure to comment on at least two of your classmates' postings. Your replies must be more than a simple phrase like "I agree" or "I like your answers". Replies should reflect on why you agree or like what has been posted. Your replies must reflect a genuine effort to engage your fellow classmates regarding the comments provided or the problem that has been solved. Please post your responses here. 1. What does centripetal mean? 2. Before circular motion was fully understood, it was thought that there was an outward force called the centrifugal force. What causes the "feeling" of a centrifugal force in a rotating object (imagine swinging a ball on a string and feeling the tension of the string). 3. What is the difference between uniform circular motion and planetary motion? 4. Why are we able to effectively model Earth's motion using a UCM model?
