Homework Help Overview

The discussion revolves around the effects of friction and heat generation when two objects, specifically books, are rubbed together. Participants are exploring how to determine temperature changes resulting from this interaction.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Some participants express confusion about the original question and seek clarification. Others attempt to explain the relationship between friction, heat generation, and subsequent temperature changes when the rubbing stops.

Discussion Status

The discussion includes attempts to clarify the question and explore underlying principles such as the law of conservation of energy and Newton's law of cooling. There is no explicit consensus, but various lines of reasoning are being examined.

Contextual Notes

Participants are addressing potential assumptions about heat transfer and the mechanisms involved in temperature changes, indicating a need for further exploration of these concepts.

Homework Statement


Rub the two books together for a long time, so that the thermometer goes all the way up to the top and all the extra molecules fly off the top book. Keep the books touching, but stop rubbing. The temperature will go down. How can you tell? List two different ways.

I have no idea what the question is. Would you mind elaborating?
 
when you rub two objects together heat is generated and when you stop heat is lost. what is the reason for this?

What do you think? What research have you done?

Are you familiar with the law of conservation of energy? What about Newton law of cooling?
