its weight
No, changing the shape or size of an object does not change its density. Density is determined by the mass of an object divided by its volume, so as long as the mass and volume remain constant, the density will stay the same.
Yes, the shape of an object can be different while still having the same mass. Mass depends on the amount of matter in an object, while shape refers to its physical structure. As long as the total amount of matter remains constant, the mass will stay the same regardless of shape.
Adding depth makes a 3D object from a 2D shape.
Inertia makes it stay still and determines how hard it would be to get it moving
yes it does help your boobs, it gives them support which makes them stay in that shape for however long.
The mystery object is cylindrical in shape.
Adding depth makes a 3D object from a 2D shape.
Shape, or also, the State of the object (i.e. fluid, plasma, solid, gas, etc.)
An object in motion tends to stay in motion.
An object can fly when the forces of lift and thrust are greater than the forces of weight and drag. Lift is generated by the shape of the object (such as wings on an airplane) and thrust is the force that propels the object forward.
Yes. (Unless you were to add to or remove form the object to change the shape. For example, a book will not have the same mass if you rip some pages out.)
The shape of an object bears no relation to the mass of an object.
