Question

what is the sensation that mass will produce under zero gravity condition? (since it won't acquire weight (w=mg, g=0) )

Answer 1

Weightlessness.

Answer 2

stormfire 1 is right. because there will be no gravity, the object, no matter what mass it is ON EARTH (will have a different mass on another planet because of the planet's gravitational pull) the object will be weightless.

Answer 3

right

Answer 4

In zero gravity, mass will produce pure inertia, without side-effect of weight having to be taken into account.

Answer 5

The mass of it would not change even in the absence of gravity. Mass is the measure of matter contained in a body. If there is no gravity acting on a body that does not mean that the substance does not contain matter. It still contains the same amount of matter and hence would have the same mass. Although the mass would feel weightless as nothing would be pulling it down(Please remember that one usually feels their weight when the normal force is acting on it). It there was no gravity and this object did somehow manage to walk around on such a surface he would experience no normal force and hence would not feel its own weight. This is similar to an astronaut orbiting the earth. People say that there is no gravity. But you have to realize that according to Newton's Law of Gravitation there has a force acting radially towards the earth acting on it. Yet the astronaut doesn't feel his own weight as there is no normal force acting on him/her and the gravitation force is used as centripetal force. Hence he feels weightless. So please don't confuse weightlessness with zero gravity.
