The four factors that affect an upthrust when body is immersed in water are :
- Upthrust depends on the volume of object immersed in the liquid.
- upthrust exerted by a liquid depends on the surface area of the solid immersed.
- upthrust developed by a liquid depends upon the surface area of the solid immersed.
- upthrust depends on the acceleration due to gravity of the place.
An object that is partly, or completely, submerged experiences a greater pressure on its bottom surface than on its top surface. This causes a resultant force upwards. This force is called upthrust . An object in a fluid is displacing some of the fluid.Upthrust = weight of the liquid displaced by the submerged part of the body Upthrust = mass of liquid displaced x Acceleration due to gravity Upthrust = volume of liquid displaced x density of liquid displaced x Acceleration due to gravity,Since volume of solid immersed is equal to the volume of the liquid displaced,Upthrust is not a type of friction. It is the upward force that a gas or liquid has on an object floating in it.
The upthrust on an object stays the same no matter how deep it goes (as long as it is completely submerged). This is because the upthrust depends only on the DIFFERENCE between the forces on the top and bottom of the object.Upwards forces from water or air are called upthrust. Things float in water because of upthrust. ... They are called non- contact forces.When a body is partly or totally immersed in a fluid there is an upthrust that is equal to the weight of fluid displaced. Upthrust = apparent loss of weight of object = weight in air - weight in liquid.
The effect of upthrust is that weight of the body immersed in a liquid appears to be less than its actual weight. There are two factors on which upthrust depends - Volume of the body and Density of the Liquid. Larger the volume of body submerged in liquid, greater is the upthrust.here is a force from the water pushing us up. This force is called the upthrust. A piece of wood floating on water, and a helium balloon floating in the air, are both effects of upthrust. ... It states that: the upthrust is equal to the weight of the fluid displaced.
density is one factor affecting upthrust (buoyant force). if the density of the substance is more than the density of the fluid, then the upthrust will be less and thus the substance sink. if the density of the substance is less than the density of the fluid, then the upthrust will be more and thus the substance float.
