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.
The upward force that fluids exert on all matter is called buoyancy. It is a result of the pressure difference between the top and bottom of an object submerged in a fluid, pushing the object upwards.

What force is an upward force that fluids exert on any object that is placed in them?
Buoyant force is an upward force that fluids exert on any object placed in them. It is equal to the weight of the fluid that the object displaces.
What 2 things exert buoyant force?
Two things that exert buoyant force are fluids (such as water or air) and objects submerged in those fluids. Buoyant force is the upward force exerted by a fluid on any object placed in it, which helps objects to float.
What is the upward force found in all fluids?
The upward force found in all fluids is called buoyant force. It is caused by the pressure difference between the top and bottom of an object immersed in a fluid, resulting in an upward force that opposes the weight of the object.
What is an upward force exerted by water and other fluids?
Buoyancy is the upward force exerted by water and other fluids on an object placed in them. This force is a result of the pressure difference between the top and bottom of the object, causing it to float or rise.
Which force in fluids allows objects to float?
Buoyant force is the force in fluids that allows objects to float. It is the upward force exerted by a fluid on an object immersed in it, counteracting the force of gravity pulling the object downward.
What is the upward force that fluids exert on all matter?
bouyant force

What is ability of a fluid to exert an upward force on an object?
Buoyant force.
What is the ability of a fluid to exert an upward force on an object.?
Buoyant force.
In a vacuum does an object have buoyant force?
No, an object in a vacuum does not experience buoyant force because there is no surrounding fluid to displace or exert an upward force on the object. Buoyant force is a phenomenon that occurs in fluids, such as air or water, and is responsible for objects floating or sinking.
What is the upward force found in all fluids?
The upward force found in all fluids is called buoyant force. It is caused by the pressure difference between the top and bottom of an object immersed in a fluid, resulting in an upward force that opposes the weight of the object.
What is an upward force exerted by water and other fluids?
Buoyancy is the upward force exerted by water and other fluids on an object placed in them. This force is a result of the pressure difference between the top and bottom of the object, causing it to float or rise.
IN what direction does a liquid exert force?
if you are asking in which direction does a liquid exert pressure on the object? then, liquid exert force in the upward direction which is called buoyancy. Brief description: when a body is partially or wholly immersed, it displaces the fluid. the displaced fluid had tendency to regain it's original position position. due to this, an upward force is exerted on the body by the displaced fluid. this upward force actiong on the the body immersed in a fluid is called upward thrust or buoyancy force or simply buoyancy.
Are you stand on floor does the floor exert an upward force against your feet how much force does it exert why are you not moved upward by this force?
Yes, when standing on a floor, the floor exerts an upward force on your feet equal to the force of gravity acting on your body. This force prevents you from sinking through the floor or falling. You are not moved upward by this force because your body weight is equal and opposite to the force exerted by the floor, resulting in equilibrium.
If everything exerts a force why do you not get pulled by it?
The objects with bigger masses exert more pulling force. However, even though all the matter around us exert a force, their masses are too small for them to exert a 'feelable' force. But yes, they do exert a force, but its negligible.
Which force in fluids allows objects to float?
Buoyant force is the force in fluids that allows objects to float. It is the upward force exerted by a fluid on an object immersed in it, counteracting the force of gravity pulling the object downward.
