🙋 In physics, we define mass as the amount of matter an object contains. The SI unit of mass is kg.

## What is the mass formula in physics?

There are several formulas used to calculate mass in physics. Some are:

• $m = F/a$;
• $m = F\times g$;
• $m = \rho \times v$; and
• $m = E/c^2$.

In these formulas, $F$ represents force, $a$ represents acceleration, $g$ is the gravitational constant acceleration, $\rho$ is density, $E$ is energy, and $c$ represents the speed of light.

The formula you choose to use is dependent on the information given. For instance, if you know the force and acceleration instead of gravity and volume, this is the formula you will use $m = F/a$.

## How do you calculate mass from density and volume?

The formula used in physics to calculate mass from density and volume is:

$m = \rho \times v$

In this equation,

• $m$ represents mass;
• $ρ$ is density; and
• $v$ is volume.

So if you need to calculate the mass of an object whose density is $54\ \text{kg}/\text{m}^3$ and volume is $80\ \text{m}^3$, here is how you will proceed:

• Start with $m = \rho \times v$.
• Substitute the values for density and volume: $m = 54 \times 80$.
• Do the math to obtain $m = 4,\\!320\ \text{kg}$.

## FAQ

### What is the difference between mass and density?

Mass is the amount of stuff (molecules) something contains, whereas density measures how tightly packed the mass of a substance is in a given space.

### What is the relationship between force, mass and acceleration?

The force, mass, and acceleration of an object are related because they directly impact each other:

• The greater the mass of an object, the higher the force it will need to accelerate it.

• If we were to increase the mass of an object, but the force remained the same, the acceleration would decrease.

• If we were to decrease the force but keep the same mass, the acceleration would also decrease.
