Define buoyancy.state the factors on which buoyant force depends?
factors: volume displaced, density of liquid displaced, and the strength of gravity.
bouyancy: look in dictionary.
The upward force exerted by any fluid(liquid,gas) on an object is known as buoyancy.
The factors are:
1)Volume displaced
2)Density of fluid displaced
3)The strength of gravity
Buoyancy is the upward force exerted by a fluid on an object immersed in it. It is responsible for making objects float or sink in a fluid. The magnitude of the buoyant force depends on specific factors. To explain further, let's follow these steps to understand the concept of buoyancy and its factors:
1. Understand Archimedes' Principle: Before delving into the factors, it's essential to grasp Archimedes' Principle, which states that an object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object.
2. Identify the factors affecting buoyant force:
a. Archimedes' Principle indicates that the buoyant force is directly proportional to the weight of the fluid displaced by the object. In other words, the more fluid displaced, the greater the buoyant force.
b. The density of the fluid: The density of the fluid in which the object is submerged affects the buoyant force. If the fluid is denser, it will exert a stronger buoyant force on the object.
c. The volume of the object: The volume of the object immersed in the fluid determines the buoyant force. Larger volumes displace a greater amount of fluid, resulting in a stronger buoyant force.
3. Formulate the equation: Combining these factors, we can express the buoyant force mathematically using the equation:
Buoyant force = Density of the fluid × Volume of the fluid displaced × Acceleration due to gravity
The density of the fluid is determined by the composition and temperature of the fluid, while the volume of the fluid displaced depends on the size and shape of the object submerged.
By understanding Archimedes' Principle and considering the density of the fluid and the volume of the fluid displaced, we can deduce the factors on which the buoyant force depends.
