What is wrong with the picture of the ship on the left? ? a03/p1/ 1. Archimedes' Principle When an object is completely or partially immersed in a ! fluid, the fluid exerts an upward force on the object equal to the weight of the fluid displaced by the object. When a solid object is wholly or partly immersed in a fluid, the fluid molecules are continually striking the submerged surface of the object. The forces due to these impacts can be combined into a single force the buoyant force. The immersed object will be lighter It will be buoyed up by an amount equal to the weight of the fluid it displaces.
