Social dynamics is the way people interact with each other when they are around one another. It is like a game of guessing what will happen, like a big puzzle. Social dynamics can involve a few people or a whole group, and it can be complicated or simple. For example, if you were in a group of friends, you might be trying to figure out who will start the conversation, how to make people laugh, who might get angry, or even who everyone can agree on to lead the group.
