Buoyancy situation of fluid statics such that Archimedes principle is applicable, and is thus the sum of the buoyancy force and the object's weight If the buoyancy of an (unrestrained and unpowered) object exceeds its weight, it tends to rise. An object whose weight exceeds its buoyancy tends to sink. Calculation of the upwards force on a submerged object during its accelerating period cannot be done by the Archimedes principle alone; it is necessary to consider dynamics of an object involving buoyancy. Once it fully sinks to the floor of the fluid or rises to the surface and settles, Archimedes principle
A Treatise Concerning the Principles of Human Knowledge is a contradiction. Some philosophers, who know that ideas exist only in the mind, assume that there are external objects that resemble the ideas. They think that external objects cause internal, mental ideas. Objection: Berkeley's principles are not consistent with science and mathematics. The motion of the earth is considered to be true. But, according to Berkeley, motion is only an idea and does not exist if it is not perceived. Answer: To ask if the earth moves is really to ask if we could view the Earth's movement if we were in a position to perceive the relation between
