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.

Get answers to the most common queries related to the Mass Formula.

Gen multiplies his mass by 9.8 metres per second squared to get his weight. His weight, according to his calculations, is 490 Newton. He then decides to stand with one foot on each of two-bathroom scales. Calculate the mass that will be displayed on each scale if his weight is uniformly distributed in this setting.

Ans. The third equation shows that weight is directly proportional to mass. Hence, the mass shown  on each scale wi...Read full

On the moon, the gravitational acceleration is only 1.625 metres per second squared. If a spacecraft lands on the moon and a rover is sent to collect soil samples, What would an 8-kg rover on the moon and on Earth weigh? On the moon and on Earth, what would the rover's mass be?

Ans. By multiplying the rover’s mass by the acceleration due to gravity,...Read full
