    Energy Friction Loss
Click For Summary

Discussion Overview

The discussion revolves around the concept of energy, particularly in the context of motion without friction losses. Participants explore whether energy can maintain constant speed indefinitely under ideal conditions, questioning the nature of energy and its implications for motion.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that if energy ignores friction losses, a mass could theoretically move indefinitely at a constant speed.
  • One participant emphasizes that energy is not a physical entity but a property of objects, which complicates the discussion about energy moving forward.
  • Another participant proposes that under ideal conditions, such as a block sliding on an infinite plane with zero resistance, it would continue to slide forever at a constant speed.
  • There is a call for clarification on the original question, indicating some confusion among participants regarding the intent of the inquiry.
  • One participant references Newton's first law of motion, stating that a body remains at rest or in motion at a constant speed unless acted upon by a force.

Areas of Agreement / Disagreement

The discussion remains unresolved, with multiple competing views on the nature of energy and its implications for motion without friction. Participants express differing interpretations of the original question and the concept of energy itself.

Contextual Notes

There are limitations in the assumptions made about energy and motion, particularly regarding the definitions of energy and the conditions under which motion occurs without resistance.

If the energy itself ignores loss resistance friction and the energy moves forward, can infinity go far at a constant speed?

If a mass is moving forwards with kinetic energy, and assuming there is no loss of energy to friction, then it will go on until the end of time, or until it hits something.

Try putting your question in another way. You have managed to confused us totally so far about what you actually want to know.

If the energy itself
Energy is not a physical thing. It's a property of other things. A block or a particle can move forward, and it can have energy, but not 'the energy itself'.

If we assume a block of some sort is sliding across an infinite plane with zero resistance of any type and without any other force applied, then yes, it will continue to slide forever at a constant speed. Does that answer your question?

Is this what you're after?
Newton's First Law of Motion said:
A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by a force.
