Density is a measure of how much mass has been fitted into a specific volume.
In matter the surface of an atom is where the Electrons (which orbit the atom) are and these electrons are almost entirely massless.
The stuff that makes the atom heavy (the Protons and Neutrons) are to be found in the nucleus/centre of the atom which is tiny compared to where the Electrons orbit - most of the atom is empty space.
Thus if you were to take an inch cube of Aluminium and a inch cube of Gold the volumes would be identical but because Gold has about 197 protons and neutrons in its atomic nucleus , while Aluminium only has 27 of these in its atomic nucleus, one cube will weigh about 7 times as much as the other.
Aluminium has a density of 2.7
Gold has a density of 19.3
This is why objects of the same size BUT MADE OUT OF DIFFERENT ELEMENTS have different weights.
What else can I help you with?
Do objects of different weights fall at different speeds?
No, objects of different weights fall at the same rate in a vacuum due to gravity. This is known as the principle of equivalence, demonstrated by Galileo's famous experiment. However, in the presence of air resistance, heavier objects can overcome it better and fall slightly faster than lighter objects.
Why do objects have different weights?
Objects have different weights because weight is determined by the mass of the object and the acceleration due to gravity. Objects with more mass will have more weight because gravity pulls on them with a greater force. Different materials and shapes can also affect the weight of an object.
Why do objects have the same size sometimes and have have different masses or weights?
No, objects do not always weigh the same. The way this is when more matter is on an object more weight. An object would weigh a different amount in a different gravitational field. For instance an object with a mass of 1 kg weighs 1 kg on earth. Its weight would be different on the moon though the mass would remain the same.
Do objects that are the same size fall at the same rate?
In a vacuum, objects of different sizes fall at the same rate because they experience the same acceleration due to gravity. However, in the presence of air resistance, objects with larger surface areas experience more air resistance and fall slower than objects with smaller surface areas.
Why do different weighted objects fall at the same rate?
Different weighted objects fall at the same rate due to the constant acceleration of gravity acting on all objects regardless of their mass. This acceleration causes all objects to experience the same rate of falling, known as the acceleration due to gravity (9.81 m/s^2 on Earth). Thus, in the absence of other forces like air resistance, objects of different weights will fall at the same rate in a vacuum.
What are some objects that have the same mass but different weights?
I believe that it is not possible to have the same mass and different weights. Unless you are on the moon with a different gravitational pull.
Do all objects fall at the same seed?
Yes - If they have the same weight. No - if they are different weights... imagine dropping a feather and a stone.
Do objects of different weights fall at different speeds?
No, objects of different weights fall at the same rate in a vacuum due to gravity. This is known as the principle of equivalence, demonstrated by Galileo's famous experiment.

Can objects have different weight but same volume?
Yes. A good example would be styrofoam and steel. The same volume of each of these substances would make for vastly different weights.
Does every solid of the same size weigh the same?
No, not every solid of the same size weighs the same. The weight of a solid depends on its density, which is the mass per unit volume. Different materials can have the same volume but varying densities, resulting in different weights. For example, a solid made of lead will weigh significantly more than an equal-sized solid made of wood.
Do all objects weigh the same amount when placed in a vaccum regardless of their mass?
No. In a vacuum, the weight of an object will be the product their mass, times the gravity. In other words, objects with different masses will have different weights.
Do objects that are the same size fall at the same rate?
In a vacuum, objects of different sizes fall at the same rate because they experience the same acceleration due to gravity. However, in the presence of air resistance, objects with larger surface areas experience more air resistance and fall slower than objects with smaller surface areas.
What were the results of Galileo's experiment on falling objects?
Galileo's experiment on falling objects showed that objects of different weights fall at the same rate, disproving the common belief at the time that heavier objects fall faster than lighter ones.
Why do different weighted objects fall at the same rate?
Different weighted objects fall at the same rate due to the constant acceleration of gravity acting on all objects regardless of their mass. This acceleration causes all objects to experience the same rate of falling, known as the acceleration due to gravity (9.81 m/s^2 on Earth). Thus, in the absence of other forces like air resistance, objects of different weights will fall at the same rate in a vacuum.
Do solid objects fall with hollow objects at the same speed?
In a vacuum, solid and hollow objects fall at the same speed due to gravity. However, in the presence of air resistance, hollow objects might fall more slowly compared to solid objects of the same mass and shape, as air resistance affects hollow objects differently.
