If a rock is sinking in water with constant speed..
how many forces are working on it?

Do you understand how buoyancy works other situations? It is usually the same:johann1301 said:i don't understand how buoyancy works in this situation... anyone?
A rock sinks due to the force of gravity pulling it towards the center of the Earth. This force is greater than the buoyant force exerted on the rock by water, causing it to sink.
The shape of a rock can affect its sinking by changing its surface area. A rock with a larger surface area will experience a greater force of buoyancy, making it more likely to float. A rock with a smaller surface area will have less buoyant force, causing it to sink.
Yes, the density of a rock can affect its sinking. Rocks with a higher density will sink, while rocks with a lower density will float. This is due to the density of the rock determining the amount of mass per unit volume, which affects the buoyant force exerted on the rock.
Other forces, such as wind and water currents, can affect the sinking of a rock by changing the direction and magnitude of the forces acting on the rock. For example, strong winds can push a floating rock towards a shore, while water currents can move a sinking rock in a certain direction.
Understanding forces on a sinking rock can be applied in various fields, such as shipbuilding, oceanography, and fishing. By understanding the forces at play, engineers can design ships and boats that are more stable and efficient in the water. Oceanographers can use this knowledge to study the movement of objects in the ocean, while fishermen can use it to determine the best areas to catch fish.
