please: a body that wheight more -a lot- than the same volume of water (for example a steel sphere), falls down to deep sea by an acceleration tha is.... about... how much meters to second per second? Who can answer me please? |

The acceleration should depend on the shape of the body. This is so because of the drag. Water can be imagined as a fluid (air too is a fluid). The gravitational force also creates an upthrust + fluid friction. Hence acceleration should be less than the "g". In certain cases (depending on the shape) it would accelerate till it reaches terminal velocity (similar to parachuting).
Somebody can correct me if I am wrong. SRINIVASAN C IYER |

In adition to the drag force, there is the weight of the equal volume of water upward on the mass. (Archimedes princilple) |
