Is bouyancy a downward force exerted by a fluid on a body placed in the fluid?
No, buoyancy is an upward force exerted by a fluid on a body placed in the fluid. This force is equal to the weight of the fluid displaced by the body, according to Archimedes' principle.
What are three factors at work when an object is placed in a fluid.?
1. Weight of the object acting always downward which is due to gravitational pull 2. Buoyant force which acts always upward which equals to the weight of the displaced fluid. 3. As the objects starts moving within fluid then viscous dragging force comes into the scene and acts always opposite the direction of motion.
What direction of pressure in a fluid where is exerted?
Pressure in a fluid is exerted in all directions. This is due to the fluid molecules pushing against each other and the surfaces of the container. The pressure at any point is equal in all directions within the fluid.
Is The pressure exerted on an object by a fluid always parallel to the surface of the object?
No, the pressure exerted on an object by a fluid is always perpendicular to the surface of the object. This is due to Pascal's principle, which states that the pressure in a fluid is transmitted equally in all directions.
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.

In a fluid that is not moving is pressure at a given point exerted equaly in all directions?
Yes, in a fluid at rest, the pressure at a given point is exerted equally in all directions. This is known as Pascal's principle, where the pressure applied to a confined fluid is transmitted undiminished in every direction throughout the fluid.
In which direction is pressure exerted in a fluid at rest?
If its in a container, pressure is downward and outward due to gravity and confinement respectively. If its on a flat surface without confinement, the pressure is exerted downwards on the surface and the boundaries are held by a combination of adhesion and cohesion.
What is boyant force?
Buoyant force is the upward force exerted by a fluid (such as water or air) on an object submerged in it. It is equal to the weight of the fluid displaced by the object and acts in the opposite direction to gravity, helping objects float.
What is the pressure exerted by a fluid is the total force exerted by the fluid divide by?
area
When will an object float on a fluid?
An object will float on a fluid when the density of the object is less than the density of the fluid it is placed in. This allows the buoyant force exerted by the fluid on the object to be greater than the force of gravity acting on the object, causing it to float.
What is buoyancy Against what other force does it act?
Buoyancy is the upward force exerted by a fluid that opposes the weight of an object placed in the fluid. It acts against the force of gravity on the object, allowing objects to float or be suspended in a fluid.
The force of a fluid that pushes an object up is called?
Buoyant force. It is the upward force exerted by a fluid on an object submerged in it, which acts in the opposite direction to the force of gravity.
