If both balls have the same dimensions, then the bouyency, or upward thrust, will be the same. This is equal to the weight of water displaced (assuming the liquid is less dense than the aluminum and iron).

Iron has a higher density than aluminum, so the iron ball will have a greater mass. It will therefore sink at a faster rate in the fluid as the aluminum ball.

UPTHRUST?

An upward force acting on an object immersed in a liquid or gas. [NOT SOLID]


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. :)


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.


Is upthrust a vector quantity?

No, upthrust is a type of force experienced by an object immersed in a fluid due to the pressure difference between the top and bottom of the object. It is a scalar quantity, not a vector.


What are the rules of upthrust?

Upthrust, also known as buoyant force, is an upward force exerted on an object immersed in a fluid (liquid or gas). The magnitude of the upthrust is equal to the weight of the fluid displaced by the object. According to Archimedes' principle, an object will float if its weight is less than the upthrust acting on it.


What is the meaning of upthrust force?

Upthrust force, also known as buoyant force, is the force exerted by a fluid on an object immersed in it, pushing the object upward. It is equal to the weight of the fluid that the object displaces. Upthrust force is what allows objects to float in a fluid.


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 the definition of upthrust in physics?

Upthrust, also known as buoyant force, is the force exerted by a fluid on an object immersed in it that opposes the weight of the object. It is equal to the weight of the fluid displaced by the object and acts in the opposite direction to gravity. Upthrust is responsible for objects floating in fluids.


What does upthrust mean in science?

In science, upthrust refers to the upward force exerted on an object immersed in a fluid (liquid or gas). It is a type of buoyant force that counteracts the weight of the object, causing it to float or rise. Upthrust is dependent on the density of the fluid and the volume of the object displaced.


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 does upthrust maen?

Upthrust, also known as buoyant force, is the upward force exerted by a fluid (such as water or air) on an object immersed in it. This force is equal to the weight of the fluid displaced by the object and helps objects float in a fluid.
