Homework Help Overview

The discussion revolves around the concept of work done in a scenario where one object pushes another, specifically examining whether the second object also does work on the first. The context involves understanding the interactions between two objects moving together, without specified conditions such as constant velocity or acceleration.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the idea of whether object 2 does work on object 1, with one participant suggesting that it does so as a resistive force. Questions arise regarding how to quantify this work and the applicability of the principle in various situations.

Discussion Status

The discussion is ongoing, with participants questioning the assumptions involved and exploring different interpretations of the work-energy relationship. There is no explicit consensus, but the dialogue indicates a productive examination of the concepts at play.

Contextual Notes

There is a lack of clarity regarding the conditions under which the objects are moving, such as whether they are at constant velocity or experiencing acceleration, which may affect the understanding of work done.

Homework Statement


Object 1 pushes on object 2 as the objects move together, like a bulldozer pushing a stone. Assume object 1 does 15.0 J of work on object 2. Does object 2 do work on object 1?

The Attempt at a Solution


My answer is yes, the object 2 does work on object 1 as a resistive force. However, how do I know the exactly work that done by the object 2?

2 objects are moving together without mention under a constant velocity or acceleration. I've no clue on this.

Work done on 2 by 1 = - work done by 1 on 2.
 
in all kind of situation?

I believe it is so in most cases.
