Two ways to find the mass of an object:
1). Compare it with an object whose mass is known, for example on a balance scale, using a set of calibrated masses.
2). Weigh the unknown mass. Since we know the acceleration of gravity on earth (9.8 meters/32.2 feet per second2), we can divide the weight by the acceleration of gravity to find the mass.

∙ 12y agoWe calculate mass using your weight. Your mass always is the same but your weight might change if you were to go to a different planet and be in a different gravitational field. Since that probably won't happen you can think of weight as being constant. Your Mass, (M) is equal to your Weight (W) divided by the acceleration due to gravity (A). M=W/A. There are many ways to calculate mass from your weight, and the method you use depends on what units you use. If you know your weight in pounds, divide that number by 32 (which represents 32 feet/second^2, the approximate accerelation you feel on earth) and you have your approximate mass in slugs, which is the American unit that goes with pounds. If you know your weight in newtons, divide it by 10 ( which represents 10 meters/second^2, the approximate acceration you feel on earth) to get your mass in kilograms. If you are like most Americans and know your weight in pounds but think of mass in kilograms not slugs, than multiply your mass in slugs by 14.6 to get your mass in kilograms.

is immeasurably enhanced by the use of a scale, coupled with the knowledge of

How many newtons does a 5-kg backpack weigh on earth?
First of all, I will tell you the quick and easy way to find the answer. The equation is 9.8 multiplied by 5. You always use the number 9.8 because that is the measurement of Earth's gravity. You use the number 5 because that is the mass of the object you are measuring. That number changes depending on the object's mass. A 5kg backpack would weigh 49 Newtons on Earth. Good luck with science or whatever you needed this for!!
How can you work out the density of a planet or star?
To find the density, you need both the mass and the radius of the planet or star. The mass can be found if the orbital radius and period of any of the body's satelites are known. If not, thth masses of most bodies can be looked up. The only way of finding the radius is to look it up or to measure it directly, or through spectroscopy. Once you have both values, you use the equation density = mass/volume. Mass is mass, and (assuming the object is spherical) volume is 4/3 * pi * r^3.
Which is the more fundamental quantity mass or weight?
Mass is more fundamental than weight. Weight depends on mass, but mass does not depend on weight. A 1kilogram object will have less weight than a 2kilogram object no matter where they both are, so weight depends on mass. However, a single object with differing weight forces, for example a 1kilogram object taken from a hill to a valley, will have constant mass, so mass does not depend on weight. This is the case because weight is proportional to the distance to the source of gravity, which on the surface of Earth is the distance to Earth's center of mass. Since the top of a hill is farther from the center than the bottom of a valley, the object on the hill will experience less weight force than the same object in the valley.
What force makes objects toward accelerate towards of the earth at 9.8 ms2?
Gravitational forceThis force can be calculated two ways:Use the Universal Gravitational force formula: F = G(m1me)/r2 (where G is a constant of 6.67 x 10-11, m1 is the mass of the object, me is the mass of the earth and r is the distance between the center of mass of the object and the center of the earth.)Use Newton's Second Law of Motion: F = ma (where m is the mass of the object and a is the acceleration due to gravity which equals -9.8 m/s2)Use #1 if the object is in outer space and use #2 if the object is on earth or relatively close to the earth's surface.Note: The gravitational attraction is mutual. It accelerates the earth and the object toward each other, a negligible consideration in most cases, but is taken into account by formula #1.
Is there a link to planet size and its gravity?
Yes. To be clear, we have to consider size and mass separately. The gravity of an object increases with greater mass, but decreases with greater distance from the center If two planets have the same mass, but different sizes (meaning they have different densities) then the larger planet will have weaker gravity because the surface is farther from the center. Traditionally, the equation for finding the acceleration due to gravity is: g=G*m/(r^2) where G is a constant calculated to get the correct units, m is the mass in kilograms, and r^2 is the square of the distance from the center of mass as measured in meters. For finding the surface gravity of a planet, us the planet's radius for r. However, you can use a shortcut of this equation by tweaking the units: g=M/(R^2) where M is mass in Earth masses and R is the radius in Earth radii. By plugging in the mass and radius of a planet relative to that of Earth, you get gravity relative to Earth's surface gravity. For example, Jupiter is 318 times the mass of Earth and has about 11.2 times the radius. If we plug that into our equation g=318/(11.2^2)= 318/125.44 = 2.53. So Jupiter's "surface" gravity is about 2.5 times that of Earth.
