About This Class
Let's explore Newton’s Universal Law of gravitation together!
Sir Isaac Newton was a real genius, he realized that the force that makes an apple fall is of the same nature than the one that makes planets turn! This was a thought from the 17nth century!
This class will present his insight and the formula that came out of it. Then, it will be your turn to be active by solving 4 exercises. In all cases, you can enjoy a detailed correction of these exercises, spiced with fascinating physical facts that rise from the Universal Law of Gravitation.
*** Content of the class ***
Video 1: The lesson itself presenting the Universal Law of Gravitation.
Video 2: Two exercises with their corrections.
Video 3: Two more exercises with their corrections.
Exercises are provided also as pdf files under two forms: Full picture (to view on a screen), or printable ( so that you can work on the exercises away from the computer). Answers are provided also in a pdf document.
*** This class is part of a larger course named “Gravity, The Basics”.***
“Gravity, The Basics” explores the elementary notions of Newtonian gravity.
Class 1: “Linear Motion” (because being comfortable with this notion will allow you to make the most of the full course). This class can be taken by itself.
Class 2: “Newton’s Universal Law of Gravitation”, which you can consider as a doorway to the deeper dive we will carry out in the next classes.
Class 3: “Gravitational Fields”
Class 4: “Circular Motion”
Class 5: “Orbital Motion”
Class 6: “Wrappingup and Gravity Quiz”
*** Level of this class ***
This class is suited for end high school and entry level University students taking Physics. Any person interested in Physics and in need of a refresher on the Universal Law of Gravitation will also enjoy this class.
