Mass, weight, volume and density
This time we will teach you the main differences between the concepts Mass, Weight, Volume and Density . Here you will find not only the definitions, but also information on how to calculate them, how to measure them, in what unit, among many other things. If you have any questions you have about the information that we will leave below, contact us and we will help you solve them.

Definition of mass
The term “mass” can be understood as the measure of the amount of matter present in something, that is, how much substance is in the object . The more matter contained by an object, the greater its mass. It is measured in kilograms or its derived units.
Mass is a scalar quantity, based on inertia. Inertia is the resistance of an object to change its state of motion when force is applied to it. Therefore, an object with greater mass has a greater tendency to resist acceleration . The mass of an object determines the heaviness of an object without gravity, which means that it remains constant because the mass does not change with change in place at any given time.
Definition of density
Simply put, density is described as the amount of mass present in a substance for a given volume. It is the basic characteristic of a substance, which explains the relationship between mass and volume (occupied space). Determine how tightly the molecules of an object are packed into the given amount of space.
The density of an object remains the same, regardless of its shape and size. Although, it can be changed if the temperature and pressure are applied to the object, but the change in density results in the change in the substance as well. The reason for the sinking or floating of most objects is their density , since objects that are less dense tend to float, while the object with higher density tends to sink.
Definition of weight
The weight refers to the pull of gravity on an object . Because gravity changes throughout the solar system from planet to planet, the weight of an object does not remain constant. For example, someone who weighs 185 pounds. on Earth it would weigh 68.45 lbs. on Mercury and 432.9 lbs. on Jupiter. This is because gravity and weight are directly related, since as the force of gravity increases or decreases, so does the weight of an object.
Definition of volume
The volume refers to the amount of space occupied by an object . Liquid volumes are measured in literals or milliliters ; Solid volumes are measured in cubic meters or cubic centimeters , which are equal. To measure the volume of a solid object, scientists place the object in a container of water and then measure how many milliliters it displaces. Then they convert it to cubed centimeters using the equation 1 mL = 1 cm ^ 3.
