- The upthrust has the following three characteristic properties :
- (i) Larger the volume of body submerged in fluid, greater is the upthrust.
- (ii) More the density of fluid, greater is the upthrust.
What are the characteristic properties of upthrust force?
Explanation: The upthrust has the following three characteristic properties : (i)
Larger the volume of body submerged in fluid, greater is the upthrust
. (ii) More the density of fluid, greater is the upthrust.
What is the principle of upthrust?
Archimedes’ principle states that the buoyant force or upthrust
is equal to the weight of fluid displaced
. An object with equal mass but a lower density occupies more volume so displaces more water; it therefore experiences a greater upthrust.
What are factors on which upthrust depends?
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. More the density of liquid, greater is the upthrust. Upthrust = Volume of body x density of liquid x acceleration due to gravity.
What are characteristics of upthrust?
Expert Answer: The upthrust has the following three characteristic properties : (i)
Larger the volume of body submerged in fluid, greater is the upthrust
. (ii) More the density of fluid, greater is the upthrust.
What are the effects of upthrust?
The effect of upthrust is that
the weight of the body immersed in a liquid appears to be less than its actual weight
. Larger the volume of the body submerged in fluid, greater is the upthrust. More the density of the fluid, greater is the upthrust.
What is upthrust in physics class 9?
Upthrust is
the upward force acting on a body when
it is partially or fully immersed in a liquid, it is also referred to as buoyant force.
What is the principle of floatation?
When any boat displaces a weight of water equal to its own weight, it floats
. This is often called the “principle of flotation”: A floating object displaces a weight of fluid equal to its own weight. Every ship, submarine, and dirigible must be designed to displace a weight of fluid at least equal to its own weight.
What is SI unit of upthrust?
The S.I. unit of upthrust is
Newton (N)
since it is a force.
What is the cause of upthrust Class 9?
Upthrust is caused due to
the upward force which is exerted by a liquid on the body which is immersed in it
.
What is Class 9 Archimedes Principle?
Class 9 Physics Gravitation. Archimedes Principle. Archimedes Principle. When
a body is immersed fully or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it
. If the weight of the water displaced is less than the weight of the object, the object will sink.
What kind of force is upthrust?
Buoyancy (/ˈbɔɪənsi, ˈbuːjənsi/), or upthrust, is
an upward force exerted by a fluid
that opposes the weight of a partially or fully immersed object.
How do you calculate upthrust?
Upthrust is the force exerted by a fluid on an object in upwards direction. That’s why up-thrust acts against the weight of an object. We know that Upthrust (U)
= weight of the liquid displaced by the submerged part of the body
. So U=mg , where m is mass of the body and g is the acceleration due to gravity.
Does upthrust depend on acceleration?
Upthrust does not depends up on the acceleration due
to gravity.
What is upthrust due to liquid?
The effect of upthrust is that
weight of the body immersed in a liquid appears to be less than its actual weight
. … Larger the volume of body submerged in liquid, greater is the upthrust.
What is Archimedes Principle in physics?
Archimedes’ principle,
physical law of buoyancy
, discovered by the ancient Greek mathematician and inventor Archimedes, stating that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid …
