Click For Summary

Homework Help Overview

The discussion revolves around the relationship between a car's speed and its weight, exploring concepts related to mass and relativistic effects. Participants are examining whether an increase in speed affects the weight of the car.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Some participants propose that weight is related to relativistic mass, while others question the implications of fuel consumption on weight. There are also inquiries about the reasoning behind these assertions.

Discussion Status

The discussion is ongoing, with various perspectives being explored. Some participants have offered insights related to relativistic concepts and the effects of fuel consumption, but no consensus has been reached.

Contextual Notes

Participants are reminded to show their own work, indicating a focus on understanding the reasoning behind their thoughts rather than simply providing answers.

why? why not?

Yes, because weight is related to relativistic mass, not rest mass? But I should really brush up on the submarine paradox before committing too strongly..
 
Yes, because gasoline is burnt and vented as exhaust. Unless it's not your normal car...
