How do we know that a fluid exerts an upward force on an object submerged in the fluid?
When an object is submerged in a fluid, the fluid exerts an upward force on the object due to the pressure difference between the top and bottom of the object. This upward force is known as buoyant force and is equal to the weight of the fluid displaced by the object. This is known as Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object.
A book weighing 10 Newtons is at rest on a flat table What is the total net force on the book?
Since the book is at rest, the net force acting on it must be zero according to Newton's first law of motion. The gravitational force pulling the book downward (10 N) is balanced by the normal force exerted by the table upward (also 10 N).
What if your weight is a force acting on the rock what force acts on you?
If you sit on a rock with a downward force of 'W' pounds, then the rock exerts an upward force of 'W' pounds on your derriere. We know that the sum of the forces on the seat of your pants must be zero. Otherwise the pants would be accelerating, either up or down.
How do you know when something will flout in a flud?
An object will float in a fluid when its density is less than the density of the fluid. This is known as buoyancy, where the upward force on the object from the fluid is greater than the downward force of gravity, causing it to float.
What will happen to an object if the frictional force opposing its motion is greater than the force pushing or pulling it forward?
If the frictional force is greater than the force pushing or pulling the object forward, the object will not be able to overcome the friction and will either move very slowly or not move at all. The object will remain stationary or have a hard time moving in the intended direction due to the frictional force resisting its motion.
What is the upward force due to fluid flow around an airplane wing?
Dont know maybe density force.
What is an upward force created by water called?
It's called the buoyant force. Or you would most likely know it as buoyancy.
When 2 birds are pulling on a worm and the worm moves toward the first bird you know that the force is what?
unbalanced force

Does Neptune have gravitational force?
Neptune is pulling you toward itself right now, even as we speak. Not only that ! You are also pulling Neptune toward you, with exactly the same amount of force. I know you are. The way gravity operates ... there is a force between every two masses in all of Creation. The force is equal on both bodies, and in the direction that moves them toward each other.
How does a fluid encased bubble 'know' which direction is Up?
If the fluid is not turbulent, then the only forces acting on the bubble are vertical ... the downward gravitational force and the upward buoyant force. Whichever force is the stronger one defines the direction in which the bubble must move.
Which force causes a soccer ball to fall to the ground after it has been kicked up in the air?
The force pulling objects back towards the Earth is gravity.

The upward force that fluids exert on all matter is?
If you place a 5-kg cinder block on a tabletop, it just sits there; it doesn't move. Compared to the tabletop, it's velocity is a constant -- zero, in this case. If an object is moving at constant velocity (even zero velocity), we know that the sum of the forces acting upon it is zero. Hence, we can say that the sum of the forces acting upon the block on the table is zero. So, what are those forces? The obvious one is weight, which is the downward force that is the product of the cinder block's mass and the acceleration due to gravity (W = mg). If weight were the only force acting on the block, it would accelerate downward; in other words, it would fall at an increasing rate. But it's not falling; it's sitting there. So, there must be a force acting upon the block in an upward direction and equal in magnitude to its weight. That upward force that exactly balances the block's weight is called the Normal force.
