## Mass Formula

The following formula is used to calculate a mass.

m = F/a

- Where F is the force
- a is the acceleration.

It can also be described as the following:

m = p X V

- Where p is the density
- V is the volume

To calculate mass, multiply the density by the volume.

## Mass Definition

Mass is defined as the amount of matter in an object. The higher the density the higher the mass.

Mass is a measure of how much matter occupies a certain space. The higher the mass, the higher the density of the volume stays the same. Mass is no to be confused with weight. Weight is a measure of force on an object due to gravity, which is a function of the mass of the object and the mass of the opposing object.

For example, on a different planet, the mass of an object is going to stay the same, but the weight of that object will change. That’s because the mass of the planet affects the weight, and that mass has changed.

## How to calculate mass

Let’s look at an example of how you could calculate mass using the equations above. The first step is to determine the density of an object. This can be done in several ways, but one of the more popular ways is through the use of buoyancy. This uses the known properties of water to calculate density.

Lets assume we find our object is 25g/m^3.

Next, we need to find how much volume our object takes up. This can be done simply by measuring the length, width, and height and multiplying those numbers. Let’s assume we find it’s 10 cubic meters.

Now using the equation above, multiply the density times volume and we get 250 grams.
