The only condition where mass can be extinguished is if it is converted into energy. When this happens it obeys the well known equation
E=mc2
no
This is known as the Schwarzschild radius. It is approximately 2.95 km per solar mass.
Yes, it is possible for a body to have non-zero mass but zero weight when in free-fall or in a microgravity environment where there is no gravitational force acting on the body. Weight is the force due to gravity acting on an object, and so in the absence of gravity, the body would have zero weight but still have mass.
If the force of gravity were to disappear suddenly, the mass of the body would remain the same, as mass is a measure of the amount of matter in an object and does not change. However, the weight of the body would become zero, since weight is the force exerted on an object due to gravity.
Center of mass is defined as the point about which the sum of mass moment vectors of all the points of the body is equal to zero.
In classical physics, weight is the force exerted on an object due to gravity. If an object has zero mass, it would not experience weight as weight is proportional to mass. So, for a body to have zero weight, it would need to have zero mass.
That is a rigid body mode of high mass that has no oscillation.
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
A body with fixed mass can have zero weight when it is in freefall or orbiting in space due to the absence of a gravitational force acting on it. This is because weight is the force of gravity acting on an object, and when the force of gravity is balanced by the centripetal force of the body's motion, the body experiences weightlessness.
Not while remaining on the surface of this planet. If you go into space, your mass will not change - but your weight will become zero.
Center of mass is defined as the point about which the sum of mass moment vectors of all the points of the body is equal to zero.
Center of mass is defined as the point about which the sum of mass moment vectors of all the points of the body is equal to zero. Center of mass = [(mass of a point object)*(distance of that point from origin)]/(Total mass) For a rigid body we need to integrate this expression.
