Gravity, The Basics
Are you curious about how the world works? Then, you are at the right place!
Gravity shapes our world, and this is what I propose we explore together in the course: ”Gravity, The Basics”:
50 videos, 4,5 hours of lessons, exercises, fun science facts and tons of tips to face exam questions.
Watch the video below to get a feel of what you can expect (3minute watch).
Access to the course
The course is available on UDEMY (pay per course) and on SKILLSHARE (subscription based) , and good news, I propose a major discount for all visitors of my website
On Udemy, you can access then full course for just 10 Euros (instead of 50 Euros). Click on the picture below to benefit from this coupon.
On Skillshare, the course is divided in 6 classes . Access the full course and get 2 month subscription free by clicking on the picture below to benefit from this coupon.
Note: Students Edouard follows on a regular basis have access to all the content for free
(they are provided with a 100% discount coupon).
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 ALevel 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…
Key notions you will learn in this course
“Gravity, The Basics” teaches the elementary notions you need to understand and apply Newtonian gravity:

Solving 1dimensional 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.
Detailed content of the course "Gravity, The Basics"
"Gravity, The Basics” is structured in 6 sections. All sections contain lessons, applied examples, exercises with detailed correction, fun science facts and anecdotes, and many tips and tricks on how to approach questions in Physics. The last section is a little different: it is composed of a general summary and the Gravity Quiz!
Section 1, “Linear Motion”, presents a stepbystep technique to solve all linear motion problems when the acceleration is constant. This class is not essential for this course, yet the resolution technique presented is an extra “weapon” for students in feeling confident when facing a physics problem that involves motion.
If you are familiar with linear motion, the SUVAT technique and are comfortable solving questions, you can skip this section. Otherwise, I recommend you view it and work on the exercises: it is truly a good investment for your study of Physics in general. Note that this section can be taken independently from the course.
Section 2, “Newton’s Universal Law of Gravitation” is usually the first notion about gravity that is taught to students. If you are familiar with this, and can solve direct application questions, you can also skip this section. If not, I strongly recommend you go through this section and the exercises before moving forward with the course: Indeed, this section can be seen as the doorway to the deeper dive that follows.
Section 3, “Gravitational Fields” is the core of this course. This section teaches first what is a field, and then dives into a detailed description of gravitational fields, gravitational field strength and gravitational field lines. It is packed with many exercises aimed at making students comfortable with these notions.
Section 4: “Circular Motion” prepares 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). As for section 1, the information provided in this section applies to many other areas of Physics (mechanics, electricity, magnetism, atomic, nuclear and particle physics).
Please note that section 4 can also be taken independently from the course.
Section 5, “Orbital Motion” discusses 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). It also discusses the 3rd law of Kepler, so useful for astronomers!
Section 6: “Wrappingup and Gravity Quiz”. You have viewed all 5 sections, and worked on the exercises? Then, it is time for the exam!
After a 5minute summary of all notions presented in “Gravity, The Basics”, 12 examlike questions are presented and corrected in detail.
