if I throw a ball of iron on the ocean, the velocity in which it will sink will be lower at the beginning and higher getting near the deepest part of it? As it may be forced by the pressure of water? (the weight of water)
Remember, when the ball is totally submerged, there is pressure forcing it to the surface, as well as pressure forcing it to the bottom. According to Newton's law of motion, it's the net force acting on the ball which causes it to move. How to figure this net force? Apply Archimedes' principle to the ball.CollinsArg said:if I throw a ball of iron on the ocean, the velocity in which it will sink will be lower at the beginning and higher getting near the deepest part of it?

If an iron object sinks to the bottom of the ocean, it would experience increasing pressure as it descends deeper into the water. This pressure would cause the iron to compress, becoming more dense and compact.
The velocity of an iron object sinking in the ocean would depend on several factors, such as the size and weight of the object, the density and temperature of the water, and any external forces acting on the object. However, in general, the velocity would increase as the object descends due to the force of gravity.
The density of water plays a significant role in determining the velocity of an iron object sinking in the ocean. As the object descends, it encounters increasing pressure from the water, which causes it to become more dense. This increased density can slow down the object's velocity as it sinks.
No, an iron object will not continue to sink indefinitely in the ocean. As it descends, the object will eventually reach a point where the density of the water is equal to its own density. At this point, the object will stop sinking and remain suspended in the water.
It is unlikely for an iron object to float on the surface of the ocean as iron is a dense material and will generally sink in water. However, if the object is large enough and has a shape that allows it to displace a significant amount of water, it may be able to float. This is known as buoyancy and is dependent on the density and weight of the object as well as the density of the water.
