Indeed, the work energy-theorem applies here: the gas exerts a force in the piston, which changes the kinetic energy of the gas particles hitting the piston. However, there is a heat source providing heat to the gas, mainting its overall internal energy.
Does the Work-Energy Theorem apply to thermal kinetic energy, or is ...
Got an answer from a different question : "Work does not always have to involve changes in kinetic energy. I believe your confusion stems from a misapplication of the Work-Energy Theorem. Work is only equal to change in kinetic energy if no potential fields are present (i.e. the Work-Energy Theorem only applies for free, rigid bodies). Gravity is one of these fields, so it is possible to do ...
The discussion revolves around the Work-Energy theorem in physics, with participants exploring its definitions, equations, and implications. The original poster presents two equations related to the theorem and questions the correct terminology regarding external work. The conversation touches on the distinctions between conservative and non-conservative forces and their roles in the theorem ...
The conversation explores theoretical approaches, particularly contrasting the work-energy theorem with conservation of mechanical energy, and addresses the complexities introduced by the movement of both the spring and the blocks.
This question is similar to: Work-Energy theorem derivation. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem.
How to understand the work-energy theorem? I took a short lecture on physics for engineering last week. The lecturer emphasized that the work done on an object will cause the kinetic energy change...
