Sound is a type of mechanical energy that is produced by vibrating objects. When an object vibrates, it causes the surrounding medium, usually air, to vibrate as well, creating sound waves. These sound waves travel through the medium and can be detected by our ears or received by devices designed to pick up sound.
More specifically, sound can be classified as a form of kinetic energy because it involves the movement of particles in the medium through which it travels. The energy carried by sound waves is transferred from one particle to another, leading to the perception of sound by humans and animals. This wave-like motion is essential for how we experience and interpret sounds in our environment.
