No, not unless they are made of the same substance. Different substances have different densities, which means that the same volumes will have different masses.
If the two objects are the same size and made of exactly the same amount of the exact same stuff then no.
My hypothesis is that after correcting for air resistance, we will find that falling objects all exhibit the same acceleration regardless of their mass, weight, shape, size, race, color, creed, or national origin, as long as they are all on the same planet.
No, they will not, unless they are the same material. Every material has a different density, and mass = density x volume
Only objects that have the exact size, shape, mass and density distribution can have the same center of mass. Any variation and the center of gravity would move. Furthermore, only objects that are geometrically symmetrical (think sphere) can have a center of gravity at their geometric center.
We cannot say that the mass is same because if objects is same weight varies but not very much, but due to some extra molecules that we cannot see with our eyes the mass varies.
Similar objects.
No, there is an air resistance which resists its motion. it depends on the shape and size of the object.
Congruent
In the absence of any other force on them other than the force of gravity, all objects, regardless of their mass, size, shape, density, color, creed, or religious, political, or gender affiliation, fall with the same acceleration. That means that with equal initial velocities, their velocities are all the same after falling for equal times.
Such objects are said to be congruent.
Two shapes that are the same size and same shape are said to be congruent. They can still vary in mass.
not always it depends
Different objects contain different amounts of matter, even if they are the same size. Therefore, two objects of the same size can have different masses.
Taste, colour, mass, density, smell, temperature, ... The list could probably go on forever.
Objects are congruent if they are the same size and shape, or an exact reflection of one another. If objects are not congruent, they are dissimilar in either size, shape or both.
Congruent objects are two or more objects that have the same shape and size, where one object can be mapped onto the other through rigid motions such as translations, rotations, and reflections. Essentially, congruent objects are identical in every way except for their position and orientation in space.
No. Heavy mass ball will fall early than light weigh ball. Because gravity works early with heavy mass body.
