If the object has the same density as water (specific gravity=1) then the weight of the object will be equal to the weight of water it displaces, so it will have neutral buoyancy and apparently weigh nothing.
If the object has a lower density than water (specific gravity<water) then it will have positive buoyancy - like a piece of polystyrene foam - and will float on the top of water. In effect the excess weigh of the water it displaces is pushing it up.
If the object has a higher density than water (S.G.>1) then it will sink, outweighing the volume of water it displaces.
Google "Archimedes Principle".
Note that the density of water can vary. Pure water has a density, or specific gravity, of 1.00, but sea water is denser due to the dissolved salt, which is why you can float more easily in the ocean. (The Dead Sea is an extreme example.)
Alcoholic drinks are less dense than water, because of the ethanol they contain, and measuring their specific gravity gives a guide to their strength.
If the weight of a body in water is zero, it means the body is in a state of neutral buoyancy where it neither sinks nor floats. This occurs when the weight of the water displaced by the body is equal to the weight of the body itself.
The weight of an object can be almost zero in space or during free fall because weight is the force of gravity acting on an object's mass. In the absence of gravity or when experiencing weightlessness, objects do not feel the gravitational force, resulting in a weight close to zero.
Depend on what exactly do you mean by 'common'. On one hand there are countless photon everywhere which has zero mass. But if you mean everyday objects, then zero weight of cause (free fall, space etc), as I don't think zero mass is even attainable at this scale.
Zero.
If the weight of a body in water becomes zero, it means that the buoyant force acting on the body is equal to the weight of the body. This implies that the body is completely submerged and in equilibrium, neither sinking nor rising.
When an objects net force is zero, its acceleration is zero. No force , no acceleration.
zero
In the context of a loss of 14 pounds, the zero indicates a baseline or starting point. It signifies that the individual began at a certain weight, and a loss of 14 pounds means their current weight is 14 pounds less than that baseline. Essentially, the zero reflects the initial weight before any weight loss occurred.
The apparent weight of a body floating in water is equal to the weight of the water displaced by the body. This is known as Archimedes' principle. The apparent weight is less than the actual weight of the body due to the buoyant force acting on it.
Zero gravity refers to the phenomenon experienced in space where the effects of gravity are greatly reduced, making objects and individuals appear weightless. This occurs when an object is in free fall, such as in orbit around Earth. Objects can still have weight in zero gravity, but they do not feel the force of gravity acting upon them.
The shed is of zero mass and zero weight
The operating weight plus (+) the cargo weight equals (=) the zero fuel weight.
