How Objects Interact

The video explores different types of forces, categorizing them into contact and non-contact forces. Contact forces include friction, tension, normal force, air resistance, and spring force, while non-contact forces cover gravity, electromagnetic, and nuclear forces. The video explains how forces can change an object's shape, speed, or direction and concludes with a summary of how forces control interactions between objects.
