They must be equal. We know that, because if the vertical forces on the object

didn't add up to zero, then it would be accelerating vertically, either up or down.

What forces are balanced when something floats?

When something floats, the buoyant force (upward force exerted by a fluid that opposes the weight of an immersed object) is equal to the weight of the object. This balance of forces allows the object to stay afloat without sinking or rising.


How can we measure the upthrust of an object?

The upthrust of an object can be measured by determining the difference between the object's weight in air and its weight when immersed in a fluid. This difference in weight is equal to the upthrust force acting on the object. It can be calculated using the formula: Upthrust = Weight in air - Weight in fluid.


How do weight and upthrust make things float?

When an object is placed in a fluid (like water), it experiences two opposing forces: weight pulling it down and upthrust (also called buoyant force) pushing it up. If the object's weight is less than the upthrust, it will float. This happens because the upthrust force exerted by the fluid is greater than the object's weight, allowing it to stay afloat.


Does upthrust reduces the weight of an object?

No, the weight and upthrust are two different forces acting on an object. If both weight and upthrust are acting on an object, the total resultant force is the two added together, but weight is solely a product of the mass (which remains unchanged, unless you take into account special relativity, but I'm guessing we're not in this instance) and acceleration acting on the given object, which remains the same.


Is weight an upthrust?

Weight is a force acting downwards on an object due to gravity, while upthrust (buoyant force) is a force acting upwards on an object immersed in a fluid. These two forces act in opposite directions but are not the same. Weight depends on the mass and gravity, while upthrust depends on the volume of the object displaced in the fluid.

What happens to the body when the upthrust is less than the weight of the object'?

An object that is COMPLETELY submerged in water has its Upthrust equal its weight, but it doesn't necessarily float, an object could be at the rock-bottom of the ocean, and it would still have its upthrust equal to its weight. This is because the upthrust is equal to the weight of the fluid displaced, and so while the objects volume remains constant, and assuming the density of the fluid it displaces is constant.. The upthrust remains constant, this is unless the object compresses and has its density altered.. I know I didn't directly answer your question, but I hope this helps.. Even if a little.


Will the sumberine float or sink if its weight is greater than the upthrust acting on it?

The submarine will sink if its weight is greater than the upthrust acting on it. Upthrust is the force pushing an object upwards in a fluid, such as water. When an object's weight is greater than the upthrust, it will sink.


What is the difference between upthrust and weight?

Upthrust is the upward force exerted by a fluid on an object immersed in it, while weight is the downward force exerted by gravity on an object. Upthrust can reduce the effective weight of an object when submerged in a fluid.


What is cause of upthrust force?

The upthrust force, also known as buoyancy, is caused by the pressure difference between the top and bottom of an object submerged in a fluid. This pressure difference creates a net force directed upwards, opposing the force of gravity acting on the object.


What has upthrust got to do with floating in water?

Upthrust, also known as buoyant force, is the force exerted by a fluid that opposes the weight of an object immersed in the fluid. When an object is placed in water, the upthrust is greater than or equal to the weight of the object, causing it to float. If the upthrust is less than the weight of the object, it sinks.


What is the upthrust needed to keep 1600n afloat?

To find the upthrust needed to keep a 1600 N object afloat, you need to consider the weight of the object. The upthrust must equal the weight of the object for it to stay afloat, so the upthrust required would be 1600 N.


What are the different types of upthrust?

Positive upthrust: when the buoyant force acting on an object is greater than its weight, causing it to float. Neutral upthrust: when the buoyant force is equal to the weight of the object, causing it to remain suspended in a fluid. Negative upthrust: when the buoyant force is less than the weight of the object, causing it to sink.
