What Is The Formula For Mass?

mass ( ) A measure of the amount of matter contained in a physical body. Mass is independent of gravity and is therefore different from weight. See Note at weight. An object’s weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.

To find the weight of something, simply multiply its mass by the value of the local gravitational field, and you get a result in newtons (N). Mass is not weight, but they are always directly proportional to each other by the value of g, whatever it may be.

1. mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume.
2. mass=force÷acceleration (m=F/a).
3. mass=weight÷gravitational acceleration (m=W/g).

Divide the weight in Newtons by the acceleration of gravity to determine the mass of an object measured in Kilograms.

The most intuitive way to think about mass is in terms of weight: if you double the mass of an object, you will double its weight at the Earth’s surface. Mass is something that an object has, and is intrinsic to it. Weight is merely the result of gravity pulling on the mass.

If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.

g is directly proportional to mass. If mass is double then g will also became double. g = GM/r^2 where G is the gravitational constant, M is the mass of the Earth, and r is the radius of the Earth. So, if the Earth’s mass doubled, g would double, therefore, so would your weight.

Therefore, the mass of an object on the Moon remains the same as its mass on Earth. But its weight gets less because the gravity on the moon is less than on the Earth.

The force gravity exerts on a person determines the person’s weight. Even though your mass would be the same on Earth and the moon, if you weigh 132 pounds (60 kilograms) on Earth, you would weigh about 22 pounds (10 kilograms) on the moon.

Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. For you imperial folks, imagine you tipped the scales at 200 pounds. Your weight on the Moon would only be 33 pounds.

If you weigh 150 pounds, the moon will exert about 0.0005 pounds of force on you. The sun, about 0.09. The change in weight is even smaller, because it’s proportional to the difference in the strength of the Moon’s/Sun’s gravity at your position vs at the centre of the Earth.

However, during the full moon, it is reflecting a lot of light back at you, and those photons are impacting your body, applying a minuscule extra push away from the Moon and towards the Earth. You would register a slightly higher weight during the full moon, than during the new moon.

Since the Moon is smaller than Earth, it has a weaker gravitational pull. In fact, the Moon only has 1/6 the gravity that Earth does. This means you weigh six times less on the Moon than you do on Earth!

If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. Your weight is zero. You are weightless.

Each cubic centimeter of empty space contains about 10-29 grams of invisible matter, or, equivalently, vacuum energy. This is almost nothing, 29 orders of magnitude smaller than the mass of matter in a cubic centimeter of water, 5 orders of magnitude smaller than the proton mass.

Jupiter

Being that it takes the weight of an object on earth and converts it to the weight on Venus, the formula is Weight on Venus= (Weight on Earth/9.81m/s2) * 8.87m/s2. To find the weight on Venus, we divide the weight on earth by the earth’s force of gravity, which is 9.81m/s2. This calculates the mass of the object.

Your weight is different on other planets because the gravity is different. You have not changed of course, so your mass is always the same. We calculate weight by multiplying mass by the gravity on the surface of the planet.

Weight is a measure of gravity’s effect on mass. It varies based on factors like your mass, the planet’s gravity, and the distance between you and the planet’s center. If you weighed 100 lbs on Earth, you would weigh only 38 lbs on Mars!

5.683 × 10^26 kg (95.16 M⊕)

For example, if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That’s because Mercury weighs less than Earth, and therefore its gravity would pull less on your body. If, on the other hand, you were on heavy Jupiter, you would weigh a whopping 253 pounds!

For most adults, an ideal BMI is in the 18.5 to 24.9 range. For children and young people aged 2 to 18, the BMI calculation takes into account age and gender as well as height and weight. If your BMI is: below 18.5 – you’re in the underweight range.
