    Confusion Energy
AI Thread Summary
Energy is defined as the ability to do work, which involves displacement and force, linking it to mass. Sound energy is a form of mechanical energy that requires a medium with mass for transmission, as it relies on the movement of atoms within that medium. Radiant energy, or electromagnetic energy, does not require mass to exist, as it can propagate through a vacuum. The confusion arises from the different forms of energy, where sound is dependent on mass while radiant energy operates independently of it. Understanding these distinctions clarifies the nature of energy in various contexts.

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.
