Does gravity affect soundwaves
I am wondering this for biology
Vanessa McLachlan
Gravity does not generally affect sound. Gravity can cause materials (like certain gases in air) to be compressed because of a difference in density. And as we know, more dense materials usually conduct sound better than less dense materials. But we generally don't see gravity as a factor in anything to do with sound.

Sound needs a medium to exist,as sound is simply vibrations within that medium.
Gravity merely acts as the force that compresses molecules to the point where they act like a fluid and so can carry sound waves. With no gravity,sound would need some other force to compress the particles together to make them act as a fluid.
In practice we can pretty much totally ignore gravitational forces on the particles while they re vibrarting as they are moved far more by the refraction caused by temperature differences in the air.

How would the gravity of mars affect the landing of a spacecraft?
Does mars' gravity affect other objects. yes it does but the gravity is 38% of the earths gravity and if doesn't affect objects then it will have no moon.
How isostatic adjustments affect isostasy?
Gravity.

Does gravity affect all or only some of the objects in the universe?
Gravity affects all of the objects in the universe, but then again, gravity doesn't affect the universe.
What affcts the speed of soundwaves in the air?
Primarily air density, so temperature, pressure, and vapor content are all factors, since they all affect air density.
Does the dark affect soundwaves?
No
What is gravity and how does it affect planets and the oceans?
gravity is something that can affect the planets.
How would the gravity of mars affect the landing of a spacecraft?
Does mars' gravity affect other objects. yes it does but the gravity is 38% of the earths gravity and if doesn't affect objects then it will have no moon.
How does gravity affect a person's height or stature?
Does gravity affect a person's height and why?
Does air pressure affect gravity?
Gravity is a function of mass and distance. So, no air pressure does not affect gravity.
How do mass of the objects affect the force of gravity?
The greater the mass, the stronger the gravity, but the distance does not affect the amount of gravity.
How isostatic adjustments affect isostasy?
Gravity.
Would Earth's gravity ever affect Pluto?
No, Earth's gravity would not affect Pluto. However, the suns gravity does.
Does Mars' gravity affect other objects?
yes it does but the gravity is 38% of the earths gravity and if doesn't affect objects then it will have no moon
How does gravity affect the object's mass and weight?
Gravity affects weight, it does not affect mass.
How does newtons law affect the force of gravity?
The law doesn't affect gravity; it describes it.
How does gravity affect gravity?
It doesn't work like that. Gravity affects MASSES.
