Group emotion is what people feel when they are in a group or when they are together with other people. It can be positive, like when people are happy and excited to be together, or negative, like when people are feeling angry or sad. Group emotion is different than individual emotion, because when people are in a group their emotions can be influenced by the group's atmosphere and the emotions of the other people in the group. For example, if one person in the group is feeling excited and happy, it can cause the others in the group to start feeling the same way. Group emotion can help people connect with one another and build strong relationships.
