vidéo : Interactions et Champs. Électrostatique et Gravitation, en //. 1e spé. PC | Contrôle continu BAC

The video is about the similarities between the Coulomb's law and the law of gravitation. It also talks about the vector expressions of the force of gravitation and the field of gravitation, the force of electrostatics and the field of electrostatics. The video also describes the local characteristics of a line of electrostatic field or gravitational field. Finally, it illustrates the electrostatic interaction.
