Mass is defined as the amount or quantity of matter in an object or body. Every object that has a weight needs to necessarily have a mass. Both living and nonliving things can have a mass. A table, desk, computer, pencil, and cricket bat has a mass. 

It is the intrinsic nature of a mass, which makes a particular object light or heavy. 

How to find the mass of an object in Physics?

In Physics, mass refers to the intrinsic weight of matter in an object. The SI Unit of mass is kg or kilogram. 

Mass = Density (D) x Volume (V)

The most interesting aspect of mass is its consistency. The value of a mass remains constant all the time. It remains the same even in times of war, famine, earthquake, and change in geographical location. 

The SI unit of mass is called Kg or Kilogram, pounds, lbs, etc. You can convert every unit of mass to other units with a conversion trick. Mass measures how a body reacts to acceleration.

How to find the mass of an object formula?

You can trace the amount of mass in an object using these ways:

Mass = Density * Volume (m= ρV) ——— (i)

Mass = Force/ Acceleration (m= F÷A) —– (ii)

The acceleration of any object is directly related to the proportional force applied to it. Similarly, the amount of acceleration that is applied to a constant force remains proportional to the mass. 

Mass = Weight / Gravitational Acceleration (M= W÷G) —– (iii)

Weight refers to the product of mass and gravitational acceleration. You can use any of the above formulae to find a mass of a given object. 

What does the mass of an object measure?

The SI unit of a mass is KG. The mass of all objects is measured in Kg. The density of an object is calculated using the Greek letter ρ, which means mass per unit volume.

Even water has a mass and density. According to a scientific estimate, one cubic meter of water will have a mass of 977 kg. Similarly, we can also estimate the mass of any object if we know its volume and density.

For example, how much mass does 0.6m3 of water has?

We can solve it as follows:

Mass = D – Density * V – Volume

Here; Mass = 0.6 * 977 = 586 kg. 

You can solve other problems relating to finding out mass in a similar manner.

A neutron star also has a mass with a heavy density. An iota of a neutron star may have a few tonnes of mass equal to 100+ times of the earth.

How does Mass and Weight Vary?

Many people and students often get confused when it comes to mass and weight. But both of them denote two different things. However, many people still use them interchangeably—which is not right.

The mass of an object doesn’t transform its location from one side to the other. On the contrary, weight refers to the gravitational field in relation to a particular object or body. The gravitational field differs from object to object. 

Moon has a low gravitational field than the earth. So, obviously, the weight of an object varies from place to place. An object weighing 100-Kg here would weigh much less on the moon. That’s how the gravitational field matters.

In Conclusion:

Great scientist Albert Einstein proved that both mass and energy are two different things using the formula ‘E=MC².’

Here, E refers to energy while M denotes mass. And C is equal to the speed of light. C is equal to 299792458 m/s (3*10^8 m/s) in vacuum. 

The above theory shows that even a small amount of mass has an overwhelming quantum of energy. Thus, it demonstrated how mass and weights are two different things and shouldn’t be used interchangeably.
