Homework Help Overview

The discussion revolves around the energy changes experienced by a cyclist traveling downhill, specifically focusing on the transition from point X, where the cyclist applies brakes, to point Y, where the cyclist comes to a stop. The subject area pertains to energy transformations in physics.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster presents multiple options regarding the sequence of energy transformations, including kinetic energy, gravitational potential energy, and internal heat. Participants engage with the question of which transformation sequence is correct.

Discussion Status

The discussion is ongoing, with participants sharing light-hearted comments while the original poster seeks clarity on the energy changes. There is no explicit consensus on the correct answer, and the conversation remains open-ended.

Contextual Notes

The original poster mentions a time constraint due to an upcoming exam, which may influence the urgency of their inquiry. There is also a reference to a marking scheme that is not available to them.

Sorry for brief formulation but have no time.

Cyclist travels down hill, no pedalling.
Applies breaks at X and stops at Y.

Which energy changes have taken place between X and Y?

A. Kinetic --> internal (Heat) ---> Grav potential
B. Kinetic --> Grav Potential --> Internal heat
C. Grav Potenial --> Internal (heat) ---> Kinetic.
D. Grav Potential --> Kinetic ---> Inetnal Heat

Thank you!

lol are you using your blackberry during a test?
 
Hahaha no I am just doing a Paper and don't have the marking scheme.
My IGCSE is tomorrow though.
So maybe that's a good idea ;D
Anyway know the answer?
 
Ya but i don't think I am suposed to say
