Objects under water seem to weigh less but they have the same mass as they would out of water.

What causes an object to weigh less when submerged in water?
An object seems to weigh less when submerged in water because the buoyancy of the water is greater than that of air, causing a force to be applied to the object, reducing the apparent net force that is required to support the object. However, gravity is gravity, and the object still weighs the same. Its just that there is an additional force acting on the object in opposition to the force of gravity. If you were to weigh a volume of water, and then weigh it again with an object in it, you would discover that the total weight did, in fact, increase by the weight of the object. Note that this is all independent of the object's mass. Mass and weight are two different things, and they should not be confused. The object's mass also does not change just because it is submerged in water. To illustrate this last point, an object in outer space does not weigh anything, because the net force of gravity is zero, but the object still has mass, and it requires the same force it always did in order to accelerate it at a certain rate.
If the mass of an object is weigh and the object is dropped in cylinder containing water but the object is not fully under water will this affect the density?
The density of what? But regardless the answer to that: Density is mass per volume. Mass is not influenced by the upward force of the fluid in which the object is submerged. The weight, on the other hand, is. Weight is a force, and mass is an amount of matter.
Will an object weigh less when it is on a planet close to the sun?
The weight of an object depends on the mass of the object and the mass of the planet. How close the Sun is doesn't really factor into things.
What You weigh the mass of an object you then cut the object in two halfs and weigh the total mass of the two halves is what to the mass of the original object?
it is equal to the mass of the original object
How is mass and weight alike?
Weight is mass, when accelerated by a gravitational pull. In space you are weightless, but still have mass. The same object will weigh less at the top of a mountain, because there is slightly less gravity. It will still be the same object and therefore have the same unchanging mass.
What is the relationship mass and the force of gravity?
Mass is a measure of how much matter something has. Weight is the effect of gravity pulling on that mass. So an object that weighs 1kg on Earth would weigh less on the Moon which has less gravity even though the mass of the object is constant. The relationship is: Force of gravity on an object in a certain place = (object's mass) x (acceleration of gravity in that place) .
How do you get the mass of the object?
An easy way to do that is to weigh the object. In principle, the mass can be derived from the weight.
If you weigh less on the moon do you have less mass?
No, you have the same mass. The reason why you weigh less is because the moon has a less gravitational pull on you since it has less mass than the earth.
What determines the mass of an objects?
The only "weigh" to determine the mass of an object is to compare it with the mass of a known object. The mass of an object is determined by force and acceleration.
How would you verify the Archimedes principle for objects that are less dense than the liquid?
Two ways to do this: 1) Floating the less dense object on the more dense liquid. To verify the Archimedes principle you need to show that the mass of the liquid displaced by the less dense object is equal to the mass of the less dense object. To do this you need to have a way to determine the mass of the displaced liquid. If the liquid is in a container filled to the brim, then when you place the less dense object in it, the displaced liquid will spill out over the edges of the container. If you can collect and weight that liquid, then you can compare its weight to the weight of the less dense object - they should match. Alternatively, you can find a way to measure the volume of the displaced liquid and calculate the mass from the volume and density of the displaced liquid. 2) Immerse the object completely in the liquid and measure the force required to keep it submerged. This one is more complicated and difficult to execute and measure. The force required to keep the less dense object submerged should be the difference between the weight of the object (when it is not in the liquid) and the weight of the displaced liquid.
What are 2 ways to find the volume of an object?
Derive from measurements of length, breadth, height, radius, diameter etc. Measure the volume of displaced liquid when the object is submerged. If the object is of a material of known density (or specific gravity), weigh it and calculate volume from volume = mass/density.
How can you weigh more on the earth than you would on the moon and still have the same mass in both places?
Mass measures how much matter there is in an object, but weight measures how much gravity acts upon it. You have the same amount of matter in both places, but you weigh less on the moon because there is less gravity.
