## What Is Mass?

The most general answer to the question of what is mass in physics is the amount of matter in an object. The larger the volume of an object, the greater the amount of matter in the object. The amount of mass of a body is always the same everywhere, it does not change; It stays the same on Earth, on the Moon, or in outer space. An astronaut who weighs 75 kilograms on Earth weighs 75 kilograms on the Moon and in space. It is not affected by temperature or pressure, it is always constant.

Also, as you’ll see in later topics, mass is a measure of an object’s inertia. Accelerating an object means that the force needed to change its velocity depends on the mass of the object; As the mass increases, the amount of force required also increases. According to Newton’s laws, the share of the applied force to the acceleration is defined as the mass.

M = ρ * v

In the SI unit system, density is kg/cubic meter (kg)

## Volume?

The answer to the question of what is volume is the place that an object occupies in space, or rather in space. Space is three-dimensional, so volume is always three-dimensional. Solids, liquids, and gases; It is common features of matter in general terms. At a certain pressure and temperature, solids and liquids have a fixed mass, while gases take up the volume of the container they are placed in, their volumes are variable.

V = ρ * m

In the SI unit system, the density is kg/cubic meter (m³).

## Density

The density of a material is defined as its mass per unit volume. It is a measurement that indicates that matter is tightly packed together. The density principle was discovered by the Greek scientist Archimedes.

To calculate the density of an object (usually denoted by the Greek letter “ρ”), the mass (m) is taken and the volume (v) is. The formula goes like this:

ρ = m / v

In the SI unit system, density is kilograms/cubic meters (kilo/m³).

## Mass, Volume, and Density Calculation Examples

**Example 1;** Calculate the sulfuric acid density if 76 m³ of acid is 65 kg.

**Step 1 : **Given information:

Density (ρ) = ? kg/m³.

Mass (m) = 76 kg .

Volume (v) = 72 m³

**Result :** ρ = 1.169 kg/m³.

**Example 2;** A block of aluminum has a volume of 20 m³ and a mass of 60 kg. What is its density?

**Step 1 :** Given information:

Density (ρ) = ? kg/m³

Mass (m) = 60 kg

Volume (v) = 20 m³

**Step 2 :** Substitute the values in the formula.

Density :

ρ = m / v

ρ = 60 / 20

**Result :** ρ = 3 kg/m³
