PS2B - Types of Interactions

Paul Andersen introduces the concept of fields and the four fundamental forces: gravity, electromagnetism, and strong and weak nuclear forces. He explains interactions between objects, both in contact and at a distance, using fields. The video covers gravitational forces, Newton's law, electromagnetism, Coulomb's law, and nuclear forces. Teaching strategies for different educational levels are also discussed, emphasizing the importance of understanding interactions and fields.
