Work Energy Power: Where Does the Energy Come From?

Click For Summary

Discussion Overview

The discussion revolves around the source of energy when pushing a bicycle up an incline, specifically focusing on the increase in potential energy for both the bicycle and the person. The scope includes conceptual understanding of energy transfer and the role of muscular energy in this process.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • One participant states that the potential energy increases as the bicycle and the person are pushed up an incline, questioning the source of this energy.
  • Another participant proposes that the energy comes from muscular energy, indicating that the effort exerted by the person contributes to the increase in potential energy.
  • A third participant reiterates the initial question about the source of energy, prompting further reflection on the topic.
  • A fourth participant suggests that the energy could be understood as a product of weight (mg) and height (h), implying a relationship between these factors and potential energy.

Areas of Agreement / Disagreement

Participants express differing views on the source of energy, with some attributing it to muscular energy while others suggest a more mathematical perspective involving weight and height. The discussion remains unresolved with multiple competing views.

Contextual Notes

Participants do not clarify assumptions regarding the definitions of energy or the mechanics involved, leaving some aspects of the discussion open to interpretation.

when you push your bicycle up on an incline the potential energy of the bicycle and yourself increases. Where does this energy come from?

Since your position is changing, you are gaining potential energy and as you are pushing the bicycle, the potential energy comes from yours muscles, I mean -muscular energy

Where do you think?

A product of your weight(mg) and your height (h)?
