The discussion revolves around the concept of mass-energy equivalence, specifically focusing on its implications in the context of relativity, including relativistic momentum and energy. The original poster expresses confusion regarding these concepts and their application in a presentation setting.
The discussion is ongoing, with participants seeking clarification on fundamental concepts. Some guidance is provided regarding the relationship between mass, speed, and momentum, but no consensus has been reached on the understanding of these concepts.
The original poster is preparing for a presentation and is seeking a clearer understanding of the topic, indicating a potential time constraint and the need for simplified explanations.
momentum is "mass times speed". Since both mass and speed are "relative", how could momentum NOT be? Likewise, energy is "1/2 mass times speed squared" so it also is relative to the viewer.skoks said:I understand this but I don't understand how momentum can be relative... What is dilated mass?How can energy be relative aswell?
