关于内容

This course is an introduction to mechanics and follows a standard first-semester university physics course. You will learn fundamental mechanics concepts and mathematical problem solving required for all STEM fields.

The course begins with kinematics, where you will learn to use equations and graphs to describe the position, velocity, and acceleration of an object, and how those quantities are related through calculus. You will then learn how forces affect motion through Newton’s Laws, and how to understand and calculate several different forces, including gravitational, normal force, drag force, and friction force. The concept of energy will be covered, including kinetic energy, potential energy, and how they are affected by work. You will learn how to use the conservation of energy to solve motion problems. Finally, momentum, another “quantity of motion” will be described. You will learn how to calculate momentum, about its relationship to Newton’s laws, and how to use it to solve motion problems, including collisions.

This course is valuable preparation for the equivalent on-campus course, or as supplementary material.

  • Kinematics
  • Work and Energy
  • Momentum and Collisions
  • Conservation laws
  • How to apply vector analysis and calculus to solve physics problems

平台

Edx

EdX est une plateforme d'apprentissage en ligne (dite FLOT ou MOOC). Elle héberge et met gratuitement à disposition des cours en ligne de niveau universitaire à travers le monde entier. Elle mène également des recherches sur l'apprentissage en ligne et la façon dont les utilisateurs utilisent celle-ci. Elle est à but non lucratif et la plateforme utilise un logiciel open source.

EdX a été fondée par le Massachusetts Institute of Technology et par l'université Harvard en mai 2012. En 2014, environ 50 écoles, associations et organisations internationales offrent ou projettent d'offrir des cours sur EdX. En juillet 2014, elle avait plus de 2,5 millions d'utilisateurs suivant plus de 200 cours en ligne.

Les deux universités américaines qui financent la plateforme ont investi 60 millions USD dans son développement. La plateforme France Université Numérique utilise la technologie openedX, supportée par Google.
