Basically, the upward force has to counteract the downward force of gravity. Thus,
the upward force has to be equal to the object's weight. There is not much
calculation to do here; just use the standard formula for weight:
weight = mass x gravity
Under normal Earth gravity, you can use 9.8 for gravity; thus, every kilogram has a
weight of about 9.8 newton, and therefore requires an upward force of 9.8 newtons
to keep it in balance.

What is the upward force on an object?
The upward force on an object is a measure of the force exerted on it in the opposite direction to gravity. It is often called the normal force and counteracts the downward pull of gravity to keep the object from falling through a surface.
Is upthrust a reactionary force?
Upthrust is not a reactionary force. It is the upward force exerted by a fluid on an object immersed in it, such as the buoyant force experienced by an object in water. This force opposes the weight of the object and helps keep it afloat.
Why does the buoyant force act upwardon an object submerged in water?
The buoyant force acts upward on an object submerged in water due to the difference in pressure between the top and bottom of the object. Pressure increases with depth in a fluid, so the pressure at the bottom of the object is greater than at the top, resulting in a net upward force. This force helps keep the object afloat.
What is a supporting force?

What is the upward force of water or air that keeps an object afloat?
This force is called buoyancy. It is the upward force exerted by a fluid on an object submerged in it. Buoyancy helps keep objects afloat by counteracting the force of gravity pulling the object downward.

When the pressure at the bottom of a submerged object is blank the pressure at the top of the submerged object a buoyant force is produced.?
When the pressure at the bottom of a submerged object is greater than the pressure at the top, a buoyant force is produced. This buoyant force is a result of the difference in pressure creating an upward force on the object, known as buoyancy, which helps keep the object afloat.
Is force always neede to keep an object moving?
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
What keeps a falling object from accelerating?
Air resistance and buoyant force are two factors that can oppose the acceleration of a falling object. These forces act in the opposite direction to the force of gravity, thus slowing down the object's acceleration.
What force keep the ship on the surface of the water?
Buoyancy is the force that keeps a ship floating on the surface of the water. It is the upward force exerted by a fluid that opposes the weight of an object immersed in it. The shape and weight distribution of a ship are designed to displace enough water to generate the necessary buoyant force to keep it afloat.
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
What is the upward force on a ship when it is in water?
The upward force on a ship in water is called buoyant force. It is equal to the weight of the water displaced by the ship, according to Archimedes' principle. This buoyant force helps keep the ship afloat.
Why do the objects float in water?
Objects float in water when the weight of the water displaced by the object is greater than the weight of the object itself. This creates an upward buoyant force that helps keep the object afloat. The density of the object and the density of the water are key factors that determine whether the object will sink or float.
