There are several answering services that also have this question or similar ones on it. From answerbag.com, the question asked was: what is upthrust?
The answers were:
* Upthrust is the upward force exerted on an object in a fluid. It arises as a result of the difference in pressure exerted by the fluid on the surface of the object at different depth. * Up thrust is the force that pushes objects up and makes them seem to loose weight in a fluid (note - a fluid means a liquid or gas) When you are standing on the ground gravity keeps you down but upthrust stops you from falling into the earths core. In a way upthrust makes things hard!! Because if it didn't exist solids wouldn't be solid.An objects density effects how it floats. * Density = Mass * ------- * Volume * Upthrust is also called buoyancy. It is the upward force produced on an object in a fluid (such as air or water). The force is equal to the weight of the fluid displaced by the object. If that weight is greater than the weight of the object, the object will float in the fluid. If it is equal, it will sit suspended. If it is less, it will sink, but the object will weigh less than it would in a vacuum. Hence, it is easier to pick up a heavy object in water than in air - the amount of displaced water weighs more than the equivalent volume of air, therefore water produces a greater upthrust.
In wiki answers the question asked was:
= What does upthrust mean? = The answer was: Upthrust is a type of force that pushes upwards
What else can I help you with?
How can the unit of upthrust can be derived?
Pascal is the s.i unit of upthrust
What upthrust is provided by a certain volume of gas?
The upthrust provided by a certain volume of gas is equal to the weight of the displaced fluid (Archimedes' principle). This upthrust helps objects float in water and is directly proportional to the volume of gas displaced and the density of the fluid.
Does upthrust increase as you go deeper into water?
Yes, upthrust, also known as buoyant force, increases as you go deeper into water because the pressure at greater depths increases due to the weight of the water above. This increased pressure causes objects to experience a greater upward force, resulting in an increase in upthrust.
What are the reason why some things float in the water?
Certain things float in water because their density is less than the density of water. If something experiences more upthrust in water than its weight(upthrust>weight) or upthrust=weight, then it floats in water.
Why does salt give more upthrust?
Salt dissolves in water, increasing the density of the water. The increased density of the water creates more buoyant force, leading to greater upthrust on an object.
How does density and upthrust compare in size?
Upthrust cancels weight out, weight is there but you do not feel it.
What is upthrust in water?
upthrust works by if you put a counter in a jug of waser slowley it should work because gravity and upthrust both together is equal so that's how it works its equal !!!
What are the factor of upthrust?
upthrust is noting but the power of water that is used to push a thing in water
Is there upthrust on an aeroplane?
Upthrust,or lift, is created under the wing when the aircraft moves forward.
What is a kid friendly definition of upthrust?
Upthrust is a force that pushes things up in water
Is upthrust a scalar quantity?
No, upthrust is not a scalar quantity. It is a vector quantity as it has both magnitude and direction. Upthrust is the upward force exerted by a fluid on an object immersed in it, and its direction is always opposite to the direction of gravity.
Is upthrust contact force?
Upthrust is a Contact Force. :)
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 force acts against upthrust?
The force that acts against upthrust is gravity. Gravity pulls objects downward, opposing the buoyant force provided by upthrust.
Why does tropical freshwater produce more upthrust that water in winter in the north Atlantic?
tropical fresh water produces less upthrust in winter than the North Atlantic because tropical water is warmer than the cold water of the North Atlantic. I need one more reason though: for homework tropical fresh water produces less upthrust in winter than the North Atlantic because tropical water is warmer than the cold water of the North Atlantic. I need one more reason though: for homework
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.
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.
