Forms of Energy - Sound energy

Sound is a type of energy, similar to heat or light, capable of performing work. This can be observed in instances such as the cracking of glass panes due to loud noise, demonstrating that sound can exert force. 

• Sound is produced when an object vibrates, causing the air particles around it to move. These vibrations travel as sound waves through the air and reach our ears, allowing us to perceive sound.
• In certain applications, such as controlling toy cars through sound, sound energy is converted into mechanical energy. This shows that sound can perform work by moving objects in response to sound signals.
• Sound energy travels through various mediums, such as air, water, and solids. The transmission of sound through different materials occurs because the vibrations from the sound waves pass through the particles in these mediums.
• The energy of sound increases with its loudness. Louder sounds generate stronger vibrations, which can have a greater impact on objects, leading to movement or even breakage in some cases. These vibrations are the result of the energy carried by the sound waves.
