The formula to calculate the average mass (AM) is:
\[ AM = \frac{M1 + M2 + M3}{3} \]
where \( AM \) is the average mass (kg), \( M1 \) is the mass of object 1 (kg), \( M2 \) is the mass of object 2 (kg), and \( M3 \) is the mass of object 3 (kg).
Average mass (AM) is the mean mass of a set of objects. It is calculated by summing the masses of all objects and then dividing by the number of objects. This measure is useful in various scientific and engineering applications to determine the central tendency of mass values.
Let's assume we have the following values:
Step 1: Sum the masses of all objects:
\[ M1 + M2 + M3 = 5 + 10 + 15 = 30 \]
Step 2: Divide by the number of objects:
\[ AM = \frac{30}{3} = 10 \]
Therefore, the average mass is \( AM = 10 \) kg.
