## Mass Formula

The mass of a physical thing is a measurement of how resistant it is to acceleration.

The amount of matter in a body is defined as its mass. The SI unit of mass is kilogramme (kg).

## Formula

The different varieties of ways to determination of the mass of an object are there:

(m= ρ/V) Mass = Density/Volume.

(m=F/a) mass = force acceleration, the acceleration of an item is directly proportional to the force applied to it, according to Newton’s second law (F=ma). As a result, the amount of acceleration experienced when a constant force is applied is inversely proportional to the mass.

Gravitational acceleration (m=W/g) is equal to mass multiplied by weight.

**Mass = Force /Acceleration**

Force = mass × acceleration

Weight= mass × acceleration due to gravity

## Solved Examples

**Example 1: On Earth, Sam weighs 1000 pounds. Sam’s weight on another planet would be 38% of his weight on Earth. On that planet, how much would Sam weigh?**

**Solution:** We know Sam’s weight on Earth is 1000 pounds, and his weight on another planet would be 38% of his current weight. As a result, Sam’s weight on another planet is 38 percent of his weight on Earth, while his weight on Earth is 0.38 of 1000 pounds, or 380 pounds.

**Example 2: An object has a mass of 6,000 pounds. Calculate the tonnage of the object.**

**Solution:** We know that one tonne equals 2000 pounds. As a result, 6000 pounds equals 6000/2000 = 3 tonnes.
