Just like we neutralize charges, is it possible to neutralize mass ? Do we have positive and negative masses?

Answer 1

While negative mass has never been observed in the universe, it is one theoretical example of "exotic matter." There are actually three kinds of mass: inertial mass, active gravitational mass, and passive gravitational mass. They have been observed to be equivalent in all known situations. If an object had negative inertial mass, it would accelerate in the direction opposite that of an applied force. If you pushed it, it would run into you. If an object had negative passive gravitational mass, it would be repelled by massive objects. If an object had negative active gravitational mass, it would repel objects (with positive mass) from it. Physicists believe that antimatter has normal, positive mass, but they haven't actually proven it.

Answer 2

In theory (which is somewhat supported by particle behavior in some of the supercollider experiments) antimatter is a type of negative mass. Antimatter also generates a reversed gravity field or warps space-time by creating a hill instead of a depression. If you placed a quantity of matter and antimatter in close proximity, their gravity fields would tend to cancel each other out, but you must be very careful not to let them come in contact with each other or else you will get total conversion of the two quantities into energy by mutual annihilation.

Answer 3

No, mass cannot be neutralised. But it is possible to neutralize weight.
you must know that:

w=mg
where,
w=weight [unit-N(Newton)]
m=mass [unit-Kg]
g=gravitatinal acceleration.

Now, mass is either positive or zero. Zero weight is possible in free-fall & in space due to g=0.Negative weight is possible in some cases, but not negative mass.

When we try to neutralize mass, it gets converted into energy, by laws of Physics.

Answer 4

UMMM OK- WELL: there are positive/negative masses. Protons are positive masses; electrons are negative masses. netrons are netral masses. your question is a bit confusing other-wise. charge is simply put as an inballance. to neutralize an im balance means to make it stable. so most matter already is stable but it's always changing. putting matter and anti-matter..changes to energy..so you are not making it neutral your making matter into something else completely.

Answer 5

no. mass is not negative or positive. so u cant obviously think of neutralizing it...as we neutralize only those things which exist in opposite forms...like charges, acids bases etc.

Answer 6

Anti-matter has positive gravity. This is known from anti-protons in cyclotron storage rings---they have to constantly boost them upwards to keep them from falling toward the earth.

The "Dark Energy" that dominates the dynamics of the Universe on large scales is a sort of anti-gravity---it pushes things apart by a kind of gravitational repulsion.

Answer 7

The answer is Yes! There is matter and anti-matter and if they (particles) meet they annihilate each other and give up energy. Mass is actually the sum of mass of elemental particles, electrons, neutrons and protons. Each know particle has or is suspected of having) an anti-particle.

Answer 8

no...u cannot have positive or negative masses....jus imagine...if u tell " i weigh -50 Kgs"...how funny...n even height cannot b neutralized..

Answer 9

Yes, use anti matter but stand a long way back because there will be a hell of a bag!

Answer 10

Not as far as anyone knows, but keep digging and maybe you'll be the one to make the breakthrough! Take a look at this:
