What Happens to Your Kinetic Energy on a Continuously Moving Ski Lift?

Click For Summary

Homework Help Overview

The discussion revolves around the concepts of kinetic and potential energy in the context of a continuously moving ski lift. Participants are exploring how energy transforms as one ascends a mountain on the lift.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to clarify whether the energy involved is kinetic or potential as the lift ascends. Questions about mechanical work and reference frames are raised, indicating a deeper inquiry into the nature of energy transformation.

Discussion Status

The discussion is active, with participants questioning the original phrasing of the problem and examining the implications of reference frames on energy considerations. There is no explicit consensus, but various interpretations and insights are being explored.

Contextual Notes

Some participants note the potential confusion in the question's wording and emphasize the importance of understanding the reference level for energy analysis.

Homework Statement



You're on a ski lift which moves continuously. If you are on a chair at the base of the mountain beginning to head up, is it potential energy or kinetic energy?

The Attempt at a Solution



From my viewpoint, this is kinetic energy being converted into potential energy as you climb the mountain on the lift. However, The question is rather confusing in nature.

You have to elaborate the "it" part.
 
Answer me this:

Did you do any mechanical work?
Did the lift do some work on you?

Be careful about the reference frame in which the energy consideration is asked.
 
Depending on your reference level, you will retain some potential energy...but, disregarding that, a lift tends to lift people up, so they are heading for higher potential energy. If you are heading for higher potential energy, you will need kinetic energy to get there.

Since the ski lift moves "continuously", what does that say about your kinetic energy?
However, The question is rather confusing in nature.
Agreed. Did you present the question word-for-word exactly as given to you?

This is not a simple case of mechanical energy being conserved. (Something is pulling the ski lift up the slope.)
