What is an example of sound energy?
Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal.
What is heat energy in simple words?
Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.
What are the main uses of sound energy?
Today’s Use of Sound Technology
- Cellular Telephone.
- Motion Picture.

How does sound affect our lives?
Sound affects our bodies. Now, sound affects us physiologically in very powerful ways. Because hearing is your primary warning sense, a sudden sound will start a process. It releases cortisol, it increases your heart rate, it changes your breathing.
How is sound used in medicine?
Sound waves can assess potentially dangerous atherosclerotic plaques, monitor chronic liver disease, and help deliver drugs to particular locations within the body. Ultrasound devices can image tumors deep inside the body, and acoustical energy can be focused upon those tumors as a way of treating cancer.
What causes sound energy?
Sound is energy vibrating through substances. All sounds are caused by vibrations—the back and forth motion of molecules. The molecules collide with each other and pass on energy as a moving wave. Sound waves can travel through gases, liquids, and solids.
What is the evidence that sound is a form of energy?
Evidence that sound is a form of energy is found in the fact that sound can do work. A sound wave created in one location can cause the mechanical vibration of an object at a different location. For example, sound can set eardrums in motion, make windows rattle, or even shatter a glass.
