Yes, the weight of an object changes when it is underwater. Although its mass does not change under water, its weight does change because of buoyancy. Objects weigh less under water, even ones that sink. Consider how you feel when you're in a pool up to your neck. You feel almost weightless. That's because water is "pushing up" on you with a force equal to the force gravity pulls down on the mass of water your body displaces when in the water. The "pushing up" is the force of the water acting on you, and we call that buoyancy. Notice that your mass did not change at all through this. Your mass is the same as it was before you went into the water.

How much more does an object weigh after it has been submerged out of water?
Submerged "out-of-water". That is not possible. It is either submerged or it is out of water. Even when an object is submerger or partically submerged it will not weigh less. The physical characteristics (weight) of the object cannot be changed. The object, when placed in water will displace a certain amount of water and the object will float if the weight of the displaced water is more that the weight of the object. The object will then sink if it weighted more that the weight of the water it displaces. That said, the actual weight of the object doesnt change but if a scale were attached to it while hanging in air, it would read greater that when the object is floating or submerged in water.
Does an objects weight change in the water?
No. Weight = mass * g, where g = 9.8 m/s2, a constant. The mass of an object does not change unless it undergoes a chemical or nuclear change. Hence its weight is a constant too. However, the "apparent weight" changes because the inherent weight is now compensated somewhat by buoyancy, acting in the opposite direction as gravity. The weight of a piece of wood in water will be completely opposed by the buoyancy and so it floats. The weight of a concrete block cannot be completely compensated by buoyancy and so it sinks. ========================
Why does the weight of an object change in water?
because water weighs more than air, and there for, the weight difference between the water + object is less, making it seem as if the object has a smaller mass. Eg. Air = 0 (because we cant weigh it, so we set it as neutral) Water = 25 Object = 100 Object out of water = 100 Object in water = 75. Making it seem lighter
How do you calculate the weight of an object under water?
To calculate the weight of an object under water, you can use the equation: Weight (in water) = Weight (in air) - Buoyant force. The buoyant force is equal to the weight of the water displaced by the object. By subtracting the buoyant force from the weight in air, you can find the weight of the object in water.
What will happen if the weight of an object is greater than the weight of the water that it displaces?
If the weight of an object is greater than the weight of the water it displaces, the object will sink. This is because the buoyant force exerted by the water on the object is not enough to counteract the object's weight, resulting in it sinking in the water.

If you change the mass of a certain object you also change its what?
If you change the mass of an object, you also change its weight. Weight is the force of gravity acting on an object, and it is directly proportional to the mass of the object.
Does water affect the weight of an object the same thing as does submerging something in water affect the weight of an object?
Yes, when the object is submerged in water then water exerts opposite buoyonci force which decrease the weight of object.
How can you change the weight of an object?
You can change the weight of an object by altering its mass or the force acting on it. Increasing the mass of the object will increase its weight, while decreasing the force acting on it will decrease its weight.
What happens when the water around objects have a force greater than the object's weight?
The water around floating object's is a measure of that object's "Displacement". For the object to float the weight of displacement must equal the object's weight. If the water around an object is of a greater weight than an object's displacement, then the object will sink.
What is water buoyancY?
The difference between an object's weight, and the weight of water with the same volume as the object.
Why might scientists measure the weight of an object rather than the weight of an object?
The mass of an object does not change , but its weight can vary.
How do you calculate the buoyant force when given the air weight of an object's weight when submerged?
To calculate the buoyant force acting on an object submerged in water, you can use the formula: Buoyant force = Weight of the water displaced = Weight of the object in air - Weight of the object in water. This formula considers that the buoyant force is equal to the weight of the water displaced by the object.
