Influx vs. radius equation, mistake in the dimensions?

Click For Summary
SUMMARY

The discussion centers on the definition of Flux in the context of physics, specifically addressing a potential oversight in a video explanation. Flux is definitively defined as energy that passes through a unit area per unit time, with units expressed as W/m² or J/(s*m²). The participants agree that the professor's explanation lacked the crucial component of "per unit time," which is essential for a complete understanding of the concept.

PREREQUISITES
  • Understanding of basic physics concepts, particularly energy and units of measurement.
  • Familiarity with the definitions of Flux in the context of energy transfer.
  • Knowledge of SI units, specifically W/m² and J/(s*m²).
  • Ability to interpret and analyze educational video content in physics.
NEXT STEPS
  • Research the concept of Flux in thermodynamics and its applications.
  • Study the relationship between energy transfer and unit area in physical systems.
  • Explore common misconceptions in physics education regarding units of measurement.
  • Review additional resources or videos that clarify the definition of Flux.
USEFUL FOR

Students of physics, educators seeking to clarify concepts in energy transfer, and anyone interested in understanding the precise definitions of physical quantities.

I do not know if that definition of Flux is covered in the video you posted, but Flux is defined as energy that passes a unit area per unit time. So Flux has units W/m2 or J/(s*m2)

Okay, so I guess that the professor missed out on unit per time. He included only the unit per area.
