According to classical mechanics, the mass of an object is constant, and cannot change. However, modern physics shows that the mass of an object can be converted into energy, and energy into mass, at high speeds. This phenomena has been proven by experiments.
According to Einstein's theory of Special Relativity you can change the mass of an object by making it travel at a speed close to that of the speed of light as this causes its mass to fluctuate. This is the only time when his second law (F=ma) does not apply.
Here are a few ways the mass could be changed: -- Glue another piece onto the object. -- Give the object a new coat of paint. -- Sand the object to remove all the dirt and grit. -- Drill holes in the object. -- Cut a piece off of the object. If the object doesn't change size or composition in some way, its mass doesn't change.
yes
No, the measured weight of an object WILL change but the mass of an object will never change regardless of the gravitational force on object.
there is no change in the mass of body
The object's mass doesn't change, no matter where it is or where it goes.
Quantities which depend on the mass of an object are its momentum, and kinetic energy.Both change if the mass changes. In addition, if the object's volume doesn't change,then its density also changes.
As mass increases acceleration decreases.
Such an object's mass would not change, or it wouldn't change significantly. Its weight will be reduced, approximately by a factor of 6.
density
I am assuming that you mean mass of an object. The answer is no, it does not change. Mass (Density) stays the same wherever the object is, only its weight will change if the force of gravity is different.
no
You can add something to an object, or take something away. Other than that, you can't really change an object's mass. Do some reading on "conservation of mass" for more details.
No. The mass of an object doesn't change (Law of Conservation of Mass), therefore its weight won't change either (weight = mass x gravity).
It's 4.2 . An object's mass doesn't change. The thing that does change is the gravitational forcethat attracts the object to another mass. The strength of that force depends on the mass of bothobjects. The force on the first object is what we call the object's "weight".
