If a body, subject to a small disturbance from a state of equilibrium tends to return to that state
If, following the disturbance, the equilibrium is reduced even more
When a body is immersed in a liquid, it will experience an upthrust that is equal to the weight of the displaced liquid
External influences (wind, waves, water properties: density, kinematic viscosity, salinity) and internal influences or the human factor (HF), which include the action of the rudder when the ship is maneuvered and loading and discharging cargoes.
Draft and trim.
Salinity and temperature.
Higher viscosity results in higher frictional resistance.
“The action of the rudder when a ship is maneuvering” is an example of HF.
