Difference Between Mass and Matter

Both Mass and Matter are two terms that help in forming the foundation of not only chemistry but also physics. Students must understand both of these concepts quite clearly as many, sometimes get confused with these two terms.

Some even use these terms interchangeably as they don’t have a clear concept of the latter.

Mass vs Matter

Mass is a measurable phenomenon, whereas matter is not a measurable phenomenon. Mass denotes the phenomena that remain the same and constant, where matter denotes the phenomena that produce an original and new substance with a new reaction. Mass cannot be seen, whereas matter can be seen and hence are noticeable.

Mass vs Matter

Mass is a significant and major characteristic of all matter. When force is applied, the smaller more the mass is, the lesser is the resultant change. The different types of the latter are inertial mass, active gravitational mass, and passive gravitational mass.

And the terms, weight, and mass though sometimes are confused with being the same, are separate phenomena.

Matter can be defined as anything, and everything that occupies space has volume and has mass. All the objects that we can see and touch, things around us are termed as matter.

The types of physical forms of matter can be either solid, liquid, or gas. Though there has been a lot of advancement in technology and science still the concept of the matter remains inadequate.

What is Mass?

Mass can be defined as an attribute of a physical body, also as a measure of its endurance to and against acceleration when a net force is utilized. Sometimes the mass of an object also helps in determining the strength of its gravitational attraction force towards other bodies or items.

The SI unit of the latter is Kg or Kilogram. Many presume that mass and weight are the same, but with reference to physics, they are not.

Although interestingly, the mass of an object is determined with the help of the measuring instruments used for weight evaluation. They prefer using the balance scale rather than the spring scale.

Many aspects can be used to measure the mass. Some of the theorists and scientists, however, have considered and theorized that the beforementioned aspects can be independent of each concerning few factors.

It is the objects’ mass that helps in determining its acceleration in the proximity of an applied force. The inertial mass and the inertia represent the property of physical bodies at their quantitative and qualitative levels, respectively.

Concerning Newton’s second law of motion, we understand that if or when a body of a constant mass (m) is subjected to a singular force (f), the acceleration (a) produced is given by f/m.


What is Matter?

Matter can be defined as any and every substance that contains matter and occupies space that has volume. The matter is composed of atoms. Such atomic matters are sometimes referred to as ‘ordinary matter.’ One can say at the matter is everything that is around us.

The properties of the latter include various attributes that can be measured. These attributes have a vast range of modifications like density, volume, length, melting point, hardness, odor, and many more factors.

Generally, properties of matter can be distinguished as either extensive or intensive. It can also be chemical or physical.

Extensive properties like volume and mass depend on the quantity of matter that is being measured.

When dealing with the matter, one also deals with physical and chemical changes. Physical changes are the term for the processes that are undertaken during the change of the appearance of a substance.

Whereas chemical changes can result in a substance changing into a new substance with a brand-new chemical formula. An example of physical change is the boiling of water, whereas an example of chemical change is a mixture of two chemicals and making a new product.

The matter is sometimes also known to be composed of antiparticles and is referred to as antimatter.


Main Differences Between Mass and Matter

  1. Mass in simple terms can be defined as the measure of the quantity of matter present in a body, whereas matter is anything and everything that contains mass and occupies space.
  2. Mass cannot be seen, whereas matter is visible hence noticeable.
  3. The measuring unit of mass is Kilogram or Kg, whereas, in the case of matter, it concerns diverse varieties of units such as volume, mass, and weight.
  4. The changes associated with mass are perpetually constant and do not change ever. But in the case of matter, it can change into a new and original product resulting from the chemical reactions.
  5. Examples of mass: The mass of Planet Mercury is 3.302 x 10 to the power 23. Examples of Matter: An apple and Water
