Discussion Overview

The discussion revolves around the concept of work done in physics, specifically examining the role of force and displacement, and whether the weight of an object influences the calculation of work. The scope includes theoretical considerations and practical applications, particularly in scenarios involving friction.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant questions whether the weight of an object affects the calculation of work done when using force and displacement.
  • Another participant explains that work is calculated as force multiplied by distance, noting that when lifting an object, the force corresponds to its weight, and that frictional forces depend on the object's weight when moving on a surface.
  • A third participant adds that weight is relevant in specific contexts, such as when calculating work done against gravity or on slopes, where the work is proportional to weight.
  • A participant expresses interest in learning about work done without considering friction and requests resources for understanding work involving friction.
  • Another participant provides a link to a website that discusses work done with friction.

Areas of Agreement / Disagreement

Participants express varying views on the relevance of weight in calculating work done, with some emphasizing its importance in specific scenarios while others suggest it may not always be a factor. The discussion includes requests for additional resources, indicating a lack of consensus on the topic.

Contextual Notes

The discussion does not resolve the complexities surrounding the definitions of work and the conditions under which weight influences calculations. There are also limitations in the assumptions made regarding friction and surface interactions.

Who May Find This Useful

Students and individuals interested in physics concepts related to work, force, and friction may find this discussion and the provided resources beneficial.

When calculating the amount of work done, using the force applied and the displacement, does the weight of the object do anything ?
 
Physics news on Phys.org


It depends - work is force * distance.

If you are lifting an object then the force is the weight.
If the object is moving on a real surface then the friction force you need to overcome will depend on it's weight.
 


Thanks both of you two:)

For now, I'm learning of work done without friction force.

Can I have a website where you can learn work done involving 'friction' please ?
