Weight may be changed, weight is also relative. Mass of an object cannot be changed unless you add or remove some of it's substance - provided that the object can be considered "the same" once this happens. Other than this - if you're talking about a definite amount of mass - it can't be destroyed, just changed.
Mass is created by the vibrational frequency the object emits. The lower the frequency; the more solid and heavy an object is. The faster the frequency; the lighter and less solid an object is. So by changing the vibrational frequency, one could change the mass of the object.
This can be done through 'injecting' certain wave frequencies (sound) to influence the change and this has been done in the past in many cultures.
The question is very broadly specified. I think you want to ask something specific, but in the way it is worded now I can only answer the following:
Yes, it is possible to alter the mass of an object via a quantum effect. Do bear in mind though that quantum mechanics governs everything at an atomic level, so every effect is in some way a quantum effect.
I might, for example, break off a piece of bread thus lowering the mass of the remaining bread. This involves breaking molecular bounds (so-called Van der Waals connections) which is a quantum effect.
Another example would be to used the photo-electric effect to eject an electron from a piece of metal via electromagnetic radiation.
Increasing the density and/or the amount of the substance of an object will cause the mass to change
The only way is to either take away apart of the object or add stuff to the object. for example an animal could eat a large meal to gain or burn body fat. exersize to loose matter
Well, you could accelerate it till it was travelling near the speed of light, in which case it's mass would increase.
But in everyday terms, you can't, it is constant
The weight of an object can be changed by breaking it
By changing the temperature as you can add anything to a pure substance.
Adding or removing mass.
I don't ducking know
Mass can only be changed if a something loses or gains a bit more stuff, the object has to get bigger or smaller.
Yes if the both are not changed proportionately, Density = mass/volume.
Since a = F / m, to change a, there must be a change either in the net force applied on the object or in the mass of the object.
The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.
mass of an object is the amount of matter in an object
No
only the mass will change, the mass is the force applied by an object.
An object's mass (m) can be changed into energy (e). Albert Einstein gave us the conversion factor - the square of the speed of light (c2). E = mc2
Mass can only be changed if a something loses or gains a bit more stuff, the object has to get bigger or smaller.
No. Mass is an intrinsic property of an object and doesn't change, regardless of the environment into which the object is placed. The weight of an object, however will change depending on the gravity acting upon it.
The same as on earth because mass remains constant everywhere if you are thinking about the "weight" then it will be changed .
Yes if the both are not changed proportionately, Density = mass/volume.
An object with mass will be accelerated by a gravitational force.If the object were (relatively) stationary, but the gravitational force changed, then the apparent weight would change.
change the density by altering the shape.
The mass of the object is changed.The mass of the larger object which is exerting the gravitational force (the earth, for example) is changed.The distance between the two is changed.
density is how dense an object is (see dense) it is calculated by dividing the mass by volume of an object. density can be changed by changing the size or shape or the object
Since a = F / m, to change a, there must be a change either in the net force applied on the object or in the mass of the object.
