Discussion Overview

The discussion revolves around the definition of work in physics, specifically whether displacement is measured during the application of force or during subsequent motion when the force is no longer applied. The scope includes conceptual clarification and technical explanation of the work-energy principle.

Discussion Character

  • Conceptual clarification, Technical explanation

Main Points Raised

  • One participant states that work is defined as the product of force and displacement and questions whether displacement is measured during the application of force or during motion after the force is removed.
  • Another participant asserts that displacement is measured during the force's application and in the direction of the applied force.
  • A further contribution emphasizes the importance of considering the correct force, noting that if an object is pushed and then moves due to friction after the push ceases, friction continues to act on the object.

Areas of Agreement / Disagreement

Participants express differing views on the timing of displacement measurement in relation to force application, indicating that multiple competing views remain in the discussion.

Contextual Notes

There is a lack of consensus on the conditions under which displacement is measured, and the discussion does not resolve the implications of friction acting after the initial force has been applied.

as scientists defines it work is the product of force and displacement i just want to ask is the displacement meusured during force application or during motion even if the force removed
thank you
 
Physics news on Phys.org
It's measured during the force's application, and the displacement is measured in the direction of the applied force.
 
thank you
 
It's important to ensure you consider the correct force though.

For instance if you push something and initiate motion so it rolls or slides away, although your push has ceased, the force of friction is still acting.
