Welcome to the Course ”Gravity, The Basics”: 50 videos, 6 sections, 4.5 hours that explore the Basics of Newtonian gravity. Hopefully you have watched the video, and you are here reading these lines to know more… But first, as promised in the video here are the promotional actions for Youtube Viewers: You can purchase the full course on Udemy by using this link https://www.udemy.com/course/gravity-the-basics/?referralCode=91F294FF9D2454F6CEE5 You can also view this course as part of a subscription program on Skillshare (On skillshare, the course is cut into 6 classes - each class corresponds to a section of the course-. By using the link below, which will bring you to the first section of the course, you can benefit of your first 2 months of subscription for free!: https://skl.sh/2UTpsI0 *** What you will learn *** “Gravity, The Basics” teaches the elementary notions you need to understand and apply Newtonian gravity: _ Solving 1-dimensional motion problems (Linear Kinematics), _ Newton’s Universal Law of Gravitation, _ What are fields, _ Gravitational fields and gravitational field strength, _ Gravitational field lines, _ Circular motion: angular velocity, centripetal acceleration and force, how to apply these notions to solve questions in physics, _ Orbital motion and the third law of Kepler. *** Who is this course for? *** This course is suited for high school students studying Physics (from grade 10 to 12). The content of this course complies with Chapter 6 of the IB Physics Program and Topics 6.2 and 11 of the A-Level Curriculum. It contains many exercises in all sections as well as exam inspired questions (especially section 6). This course is a very valuable tool for preparing any upcoming physics exam that may have questions related to gravity. This course is also suited as a refresher for early university students that wish to solidify their understanding on Newtonian gravity. And of course, any person interested in physics and in how the world works will also enjoy the voyage: I often invite my students on adventures beyond the academic… *** Structure of the course *** “Gravity, The Basics” explores the elementary notions of Newtonian gravity. Section1: “Linear Motion” (because being comfortable with this notion will allow you to make the most of the full course). This class presents a step-by-step technique to solve all motion problems when the acceleration is constant. This Section can be taken by itself. Section 2: “Newton’s Universal Law of Gravitation”, which you can be seen as a doorway to the deeper dive we carry out in the next classes. Section 3: “Gravitational Fields”, the core of this course: This class teaches first what is a field, and then dives into a deep description of gravitational fields, gravitational field strength and gravitational field lines. It is packed with many exercises aimed at making the student comfortable with these notions. Section 4: “Circular Motion”, prepares you for the section on orbital motion. You are presented with a detailed explanation of fundamental quantities that occur in circular motion (angles, angular velocity, centripetal acceleration and forces). This Section can be taken by itself. Section 5: “Orbital Motion”, for you to master the motion of bodies in circular orbits around a massive object: This section blends notions taught in section 3 (gravitational fields) with notions presented in section 4 (circular motion), in order to get a good grasp of what is an orbit, and how to manipulate easily orbital motion concepts. Section 6: “Wrapping-up and Gravity Quiz”. Once you have viewed all 5 sections, it’s time for the exam! After a 5-minute summary of all notions presented in “Gravity, The Basics”, 12 exam-like questions are presented and corrected in detail. *** Level of this Course *** This course is suited for end high school and entry level University students taking Physics. Any person interested in Physics and in need of a refresher about gravity will also enjoy the course. Now, Enjoy the Voyage! Edouard Reny, Private Tutor in Physics (https://www.physics-tutor.nl/)
