something that does not move is unable to indicate that it possesses mass?

Hi. Using rest mass allows you to discount relativistic effects. Normal objects with zero rest mass travel at "c".

The rest mass is the energy contained by simply having mass, E=mc^2. This is the minimum amount of energy an object with mass can have. When it is moving it has more energy.

If it doesn't move then it's not being attracted by gravity to any other mass.
Two objects will attract one another (by gravity) only if they have mass.
I would go further and say that if an object is not being influenced by gravity, it has zero mass.

it doesn't mean that something which don't show any movement is massless as their is no proportanality b/w mass and velocity.
