Brownian movement, Brownian motion, or pedesis is the random movement of particles suspended in either a liquid or a gas. This is the movement that you see when sunlight is streaming through a window and you see the dust particles randomly moving. This movement helped to prove the existence of atoms and molecules. Many scientists, including Albert Einstein, used this motion to describe movements in the Stock Market, among other things!

What is a compressional wave caused by colliding air molecules?

Sound Waves


Compressional waves caused by colliding air molecules?

Compressional waves caused by colliding air molecules are known as sound waves. These waves travel through the air by creating areas of high pressure (compression) and low pressure (rarefaction), which result in the perception of sound. The frequency of these compressional waves determines the pitch of the sound, while the amplitude determines the volume.


Which sense responds to the energy caused by movement of air molecules?

The sense of hearing responds to the energy caused by movement of air molecules. Sound waves are created when air molecules vibrate and these waves are detected by the ear, allowing us to perceive sound.


Describe how sound waves are travel?

Sound waves are caused by vibrations and travel as longitudinal waves which cause by the vibration of the molecules in air (the molecules dont actually move)


Water waves are caused by wind which is directly caused by the?

The movement of air molecules. As air flows over the surface of the water, it transfers energy that causes ripples and waves to form.


What is caused by the collisions of air molecules around you that produces the force of an area?

What form of friction is air?

Air resistance is a type of friction that opposes the motion of objects moving through the air. It is caused by the molecules in the air colliding with the surface of the object, creating a drag force that slows the object down.


Is air a source of resistance?

Yes, air can provide resistance to objects moving through it. This resistance, known as air resistance or drag, is caused by air molecules colliding with the moving object and can slow down its motion.


What are waves in the air caused by vibrations?

Waves in the air caused by vibrations are known as sound waves. When an object vibrates, it disturbs the surrounding air molecules, creating compressions and rarefactions that travel through the air as sound waves until they reach our ears, where they are perceived as sound.


Does heat lesson air friction?

No, heat does not lessen air friction. Air friction is mainly caused by the molecules in the air colliding with an object as it moves through the air. Increasing temperature can actually increase air friction because it causes air molecules to move faster and collide more frequently with the object.


Do sound waves have mass?

Waves do not have mass and volume. They transmit energy without transmitting mass. However, waves can be found in solid materials such as earthquakes.
