it feels smooter
Because it is lighter.
Yes, a small object can have more density than a large object if the small object has more mass compared to its volume. Density is calculated as mass per unit volume, so an object with greater mass and smaller volume will have higher density.
An object with a high density, such as a lead ball, can have a small capacity (volume) but a large mass. This is because density is the ratio of an object's mass to its volume, so objects with high density have a lot of mass packed into a small space.
A small object with high density, such as a lead weight or a dense metal ball, would have a small capacity but a large mass due to the arrangement of its particles.
An object is stable if the centre of mass of the object is above the base area. A small perturbation of the object is more likely to push the centre of mass outside the base area if it is small.
Not necessarily. The size of an object is not directly proportional to its mass. For example, a small object made of dense material could have more mass than a larger object made of less dense material.
The density of an object is directly correlated with the amount of mass contained in the object. For example, a small object containing a large amount of mass has more density than a larger object with a smaller amount of mass.
According to Newton's second law of motion, the acceleration of an object is dependent on the net force acting on it, not its mass. If the net force acting on both objects is the same, they will both experience the same acceleration, regardless of their mass. This means that a large mass object and a small mass object can have the same acceleration if the force acting on them is equal.
The object accelerates.
Density is not the same as mass. Density is mass divided by volume.Density is not the same as mass. Density is mass divided by volume.Density is not the same as mass. Density is mass divided by volume.Density is not the same as mass. Density is mass divided by volume.
In a way that's what dense means. If something is dense then a small volume of it will have lots of mass. Something that has lots of mass will be subject to considerable gravitational force, which is weight.
There is no such object since a milligram is a measure of mass, not of weight. A small ant would have a mass of 1 mg.
