No. The speed an object will fall in water depends on: 1) The mass of the object compared to the volume of water displaced 2) The hydrodynamic friction between the water and the objects motion 3) The local gravity. For example: A 10cm sphere of iron has a density of 7.8 and a mass of 4.08kg. The mass of water displaced is 0.52kg. Gravity exerts a downward force of 40.0N downwards on the sphere, while the water exerts an upwards force of 5.1N due to bouyancy. This means that there is an initial downward force of 34.9N downwards on the iron sphere. A 10cm sphere of glass has a density of 2.5 and a mass of 1.31kg. Gravity exerts a downward force of 12.8N downwards on the sphere, while the water exerts the same 5.1N upward bouyancy force. This means that there is an initial downward force of 7.7N downwards on the glass sphere. Both spheres will accelerate in water according to F=ma, where (F) is the force exerted, (m) is the mass and (a) is the acceleration. For the iron sphere, the initial acceleration is 8.6m/s2 while for the glass sphere the initial acceleration is 5.9m/s2. This difference is due to the bouyancy force of the water which is the same for both spheres, even though the masses are different. As the spheres accelerate, the drag force of the water will increase from zero to some value which equals the net gravity force calculated above. The drag coefficient will vary somewhat with the speed but it can be considered the same for both spheres if they are both the same smoothness. Since the forces are different, the steady state speed (terminal velocity) will be different for each sphere. A 10cm sphere of balsa wood has a density of 0.1 and a mass of 0.05kg. Gravity exerts a force of 0.5N downwards while the water exerts the same bouyancy force of 5.1N upwards. Thus the balsa sphere accelerates upwards rather than downwards because the water it displaces is heavier than it and squashes it up. It will have a terminal velocity in the upwards direction. By contrast, in a vacuum, there is no bouyancy force as nothing is being displaced so (F) is proportional to (m) and thus (a) is constant. In this case all the spheres would accelerate at the same speed. In our atmosphere, the bouyancy force of air is very small, so objects may appear to fall at the same rate when in fact they are very slightly different. A hydrogen sphere would rise in air, just like a balsa sphere rises in water.

How do all objects fall?
Objects fall through the force of gravity.
Why does objects fall in different speeds?
all objects fall at the same speed because i like ponies
Do solid objects fall with hollow objects at the same speed?
Yes, if they have the same volume.
how do objects fall when there is no air resistance?
In the absence of air resistance (friction) objects will fall at the same speed. Hope this still helps :)
What things fall through?
Contracts, both social and legalDeal NegotiationsPlansLoan ApplicationsMore literally, objects may fall through other objects.Other comparisons include:People fall through cracks (in society's safety net)water (or other liquids) falling through a sievewords fall through people

Why heavier objects fall faster than do lighter objects?
They don't. All objects fall at the same rate of speed because of weight.

Yes, if they have the same volume.

What objects fall at the same speed?
Neglecting air resistance ... all of them.
Who said that objects fall at the same rate of speed and challenged the teachings of the church?
Galileo said any two objects in a vacuum will fall at the same rate.
Who found that all objects fall at the same rate of speed in a vacuum?
Galileo
Do all objects fall to the earth at the same speed?
no depening on how heavy it is that's the speed it will go. information by wwtpody:)
What is the word that causes all objects to fall at different speeds?
In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.
Does water affect how fast something falls?
Yes, however, even air affects how fast something falls. The weight of the water is what causes buoyancy (certain materials to float), and and the resistance of water plays a small role - the weight of the water being the larger role - in what causes other materials to fall slower than they would through air. There are actually certain things that are buoyant in the air, like helium. You will notice that if you let all the air out of your lungs, you will fall down through the water at a certain (very slow) speed. That speed is your terminal velocity through water. The terminal velocity of an average sized human through the air is about 55.6 m/s (200 kph or 124 mph). This speed is obviously much higher than the speed at which something falls through water. So water does affect haw fast something falls. "But wait, certain objects appear to fall through the water at the same speed that they fall through the air!" To explain this, water affects how fast something falls - compared to how fast it falls through the air - depending on its density. The object which you're talking about, is actually falling slower through the water, you just can't tell. We see this property in air too, why do you think a pound of feathers falls much slower than a lead weight?
