What will you learn All fluids exert a force that is upward on object on the fluid. The weight of the fluid displaced by the object is equal to the buoyant force on an object. The measurement of mass and volume can be calculated by volume. To change the over all density of an object an object must have a change in shape, volume, mass. Buoyant force and fluid pressure buoyant force is when all fluid pressure exert on a upward force. The upward force that keeps an object floating on a object is called buoyant force . Difference in fluid pressure can cause buoyant Buoyant force and fluid pressure continued Archimedes was a Greek mathematical who discovered how to find buoyant force. Archimedes stated that the the buoyant force on an object in a fluid is an upward force that equal to weight of the volume of fluid that the object displaces Weight vs. buoyant forces An object in a fluid will only sink is the object weight is greater than the buoyant force. An object will only float when the buoyant force on the object is equal to the objects weight. Determining density you need to to know the objects mass and volume to determine the density of an object one way to find a mass of an object is to use palit multiplying the lenth is used to find the volume of a regular such aas a cube Determining density continued to find the volume of a regular solid use water displacement by

Science Fiction and Fantasy Essay

whether it is possible to distinguish between fantasy and true science fiction. I am reminded of the analogy, attributable I believe, to Theodore Sturgeon, of the elf ascending vertically the side of a brick wall. In a science fiction story the knees of the elf would be bent, his center of gravity thrown forward, his stocking cap hanging down his neck, with his feet quite possibly equipped with some form of suction cups. In a fantasy, on the other hand, the elf would simply stride up the wall in a normal…

Density and Salt Essay

centimeter (cm3). In other words, if you filled a 1-cm x 1-cm x 1-cm box with freshwater, the water inside the box would have a mass of 1 g. Adding salt to the water increases the density of the water, because the salt increases the mass without changing the volume very much. With enough added salt, the saltwater solution density is higher than the egg's, and the egg will then float, as shown in Figure 1 below. The ability of something, like the egg, to float in water or some other liquid is known as…

Ariestotle Philosophy Essays

following Plato’s death, Aristotle began to read more empirical books and shifted from Platonism to empiricism. His main belief was that all of people’s concepts and all of their knowledge were ultimately based on perception. Aristotle’s views on natural sciences, including philosophy of the mind, body, sensory experience, memory, physics, and biology represent the groundwork underlying many of his works. When it came to physics, Aristotle believed that there were 5 elements in the universe. They are earth…
