Why ship doenot sink in ocean?
Ships don't sink in the ocean because the air pressure pushes the ship upward and keeps it buoyant-------------------------------- Ships don't sink because the overall density of the ship is lower than the density of the salt water and it displaces its weight's equivalent of water using only a portion of the ship's volume.
Does a sunken ship sitting on the ocean floor have a buoyant force on it?
Yes, a sunken ship on the ocean floor experiences a buoyant force pushing up on it that is equal to the weight of the water displaced by the ship. This buoyant force helps to keep the ship in place on the ocean floor despite its weight.
What is the average density of seawater?
The density of surface seawater ranges from about 1.020 to 1.029 g·cm-3, depending on the temperature and salinityThe average density of seawater at the surface of the ocean is 1.025 g/ml; seawater is denser than freshwater (which reaches a maximum density of 1.000 g/ml at a temperature of 4°C) because of the added mass of the salts.
Why can a ship load more in the summer than winter?
Ships can load more in the summer than in the winter because water density decreases as temperature increases, making it less buoyant. This means that ships can sit lower in the water during warmer months, allowing them to carry more cargo without exceeding their weight limits.
How does forcing air into the ballast tanks cause the ship to rise?
Action and reaction , the ship is lighter from the discharged ballast- so it will float upwards with buoyancy. One assumes you are talking about submarines. Some surface ships have trim tanks to compensate for cargo compartments not being balanced- etc. but this is not a submergence device.
What forceis exerted by water in order for the ship to float?
An upthrust force which is proportional to the weight of the ship being displaced on the water.this can simply be regarded as principle of floatation
How is a ship made of materials that are much denser than water able to float on water?
A floating ship displaces its weight in water and the water pushes back (according to newton's 3rd action-reaction law). The upward force is called upthrust. This occurs according to Archimedes' Principle which states that when a body is full or partially submerged in a fluid (water), the upthrust equals the weight of the water displaced.

Why aship floats on a water?
Because the weight of ship balances the upthrust force , We know that weight always act downward and upthrust force always act upward so we can say that it comes in equillibrium condition . that's why it keeps floating on water..........
Why do large cruise ships float in water?
Large cruise ships float in water because of a principle called buoyancy. The shape of the ship's hull displaces an amount of water that weighs more than the ship itself, causing it to float. This buoyant force counteracts the force of gravity, allowing the ship to remain afloat.
What makes ship not to sink in water?
It's the way how the ship is built. The ship in the water is able to fully displace water equal to it own weight, so that the water exerts a greater upthrust on the ship, than the ship is able to exert on the water with its weight. The net upthrust results in the ship staying afloat. If at any point the ship is not able to displace an amount of water equal to its weight, it will keep sinking until EITHER the ship finally displaces the right amount of water and begins to float OR the ship cannot displace enough water and becomes completely submerged, and sinks to the bottom of the body of water.
There are two reasons why tropical freshwater produces less upthrust than water in winter in the north atlantic but what are they?
In tropical seas the water is warmer so it is less dense than in colder areas. The ship sinks lower in water, as cargo is loaded, to displace a greater weight of water. Fresh water also produces less upthrust than sea water.
What force causes objects to float on water?
The force that causes objects to float on water is buoyancy. Buoyancy is the upward force exerted by a fluid (in this case, water) that opposes the weight of an object placed in the fluid. If the buoyant force is greater than the weight of the object, the object will float.
How many forces act on a ship?
There are typically three forces acting on a ship: propulsion force generated by engines to move the ship forward, drag resistance from water that opposes the motion, and buoyancy force that keeps the ship afloat by displacing water equal to its weight. Additional forces like wind, waves, and currents can also affect a ship's motion.
How does the presence of salt in water affect the upthrust of the water on a ship?
The presence of salt in water increases the density of the water, which in turn increases the buoyant force acting on the ship. This increased buoyant force helps support the weight of the ship, allowing it to float more easily compared to freshwater.
Why ship is floating?
An object in water displaces its weight in water. If its volume is greater than the volume of water displaced this way, it floats. Ships, despite being made of heavier materials, utilize their size and their relative empty insides to float this way.
What factors determine how low a ship will float in water?
The buoyancy of the ship, the cargo onboard, the state of the ship, the temperature of the water, the weight, the strength of the waves/up and down movement, etc.
