What is Average Mass?
Average mass is the arithmetic mean of multiple mass values. It represents the central tendency of a set of masses and is commonly used in physics, chemistry, and statistics to find the typical mass value from a group of objects.
How to Calculate Average Mass
To calculate the average mass of objects:
- Add all mass values together
- Divide the sum by the number of objects
- The result is the average mass
Average Mass Formula
The formula for calculating average mass is:
$$
\text{Average Mass} = \frac{M_{1} + M_{2} + M_{3}}{3}
$$
Where:
- M₁ = Mass of first object
- M₂ = Mass of second object
- M₃ = Mass of third object
Average Mass Calculation Example
If you have three objects with masses of 12 kg, 45 kg, and 33 kg:
$$
\text{Average Mass} = \frac{12 + 45 + 33}{3} = \frac{90}{3} = 30 \text{ kg}
$$
The average mass is 30 kg.
Applications of Average Mass
