SUMMARY

The discussion centers on the nature of energy, specifically addressing the confusion surrounding sound energy and radiant energy. Energy is defined as the ability to do work, which involves displacement and force, linking it to mass. Sound energy is classified as mechanical energy, requiring a medium with mass for transmission, while radiant energy refers to electromagnetic energy, which does not necessitate mass. The distinction between these forms of energy clarifies their respective properties and behaviors.

PREREQUISITES
  • Understanding of basic physics concepts such as energy, work, and force.
  • Familiarity with mechanical energy and its characteristics.
  • Knowledge of electromagnetic waves and their properties.
  • Concept of mass and its role in energy transmission.
NEXT STEPS
  • Research the principles of mechanical energy and its applications.
  • Study the properties of electromagnetic waves and radiant energy.
  • Explore the relationship between mass and energy in different contexts.
  • Learn about sound energy transmission and the mediums required for it.
USEFUL FOR

Students of physics, educators explaining energy concepts, and anyone interested in the fundamental principles of energy and its various forms.

energy question... end my confusion please?

energy is the ability to do work..work is displacement and force..force is acceleration and mass...that leads me to the conclusion that energy requires mass...but how about sound energy..i am 99.9 % sure that sound doesn't have mass, then why is there such a thing as sound energy? and what about radiant energy... I am also quite sure that em waves don't have mass..

sorry if youre bothered by my foolishness..but if you have an answer that could end my confusion, please post it. i would definitely appreciate it. :D

Energy comes in many forms. Mostly you're talking about mechnical energy, but the radiant energy is electromagnetic energy.

Sound is the transmission through a medium - mechanical energy. It is the atoms of the medium that do the moving. Sound cannot travel through anything (such as vacuum) that does not have mass.
