#DidYouKnow: The Moon's gravity is much less than the Earth's gravity - approximately one-sixth. So, a 100 kg astronaut weighs 980N on Earth. On the Moon, the astronaut would weigh only 162.2N. However, the astronaut's mass is 100kg where-ever they are.

Good question. You can determine your mass without depending on gravity, by using a spring. The spring applies a known force as a function of the strain from its neutral unloaded position. A mass on a spring will vibrate in simple harmonic motion, where the period depends on the spring stiffness k, and the total effective mass of the load M. You also have to account for the effective mass of the unloaded machine, that we'll call m0, and the total mass is M=m+m0. The period becomes T=2*pi*sqrt((m+m0)/k). You measure the period when it is unloaded to determine m0, and then you measure the period with the sample mass added to the system, and solve for m. Effectively, it measures inertia instead of gravitational mass. This is how astronauts measure their mass in space. Because we live in a gravitational field, it is much more convenient for us to take advantage of it, by using weight as a proxy for mass. You can either measure the support force in a scale and then divide by the known g-value of Earth to get m. Alternatively, you use a balance with a known reference mass, and compare weight-to-weight.

If mass of an object is directly proportional to its weight, then it means that the greater mass the faster an object is pulled down toward the center of Earth. But on the other hand we know that in vacuum all the objects fall down with an equal acceleration independently of their masses. Doesn't it contradict to the statement that mass is directly proportional to the weight?
@nikiwiki2006

Tural Nasibov It’s only pulled down by gravity. Mass is not a Force. W=mk(9.807)
@carultch

No it doesn't contradict the statement. There are two proportionalities to mass that ultimately cancel out of the equation. The force of gravity is proportional to mass (gravitational mass), and meanwhile the force needed to cause a given acceleration is also proportional to mass (inertial mass). Since gravitational mass and inertial mass come as a package deal, this proportionality to mass cancels out of the equation. "Everybody brought mass to the party". We are left with the fact that the free fall acceleration of gravity only depends on the local gravitational field of the environment. Which itself is a function of the mass and size of the planet.

Physics can be easy to understand, since the rules are ultimately objective. We may discover more information about the rules as new physics is researched, but the intent is to simplify it to as few fundamental rules as possible, so that any situation can be understood from the fundamental rules. Many concepts you learn in physics are shortcuts, that can be proven mathematically from more fundamental rules. Such as using the trade of potential and kinetic energy as a shortcut to solve mechanics problems, instead of solving them from first principles like N's 2nd law and kinematics fundamentals. English however, is subject to centuries of evolving social conventions that created a mess of inconsistent rules, and it is impossible to teach someone to always be able to pronounce any word given its spelling, or use that word in a sentence, without a hell of a lot of unnecessary memorization. There are always exceptions to every rule in English.

• Mass is just the measure of matter & quantity contained in object. It matters when accelerating, retarding while moving. I.e. Inertia. • Whereas weight is just the force acting on the same mass by some force of attraction (or gravitational field). On earth it is earth's gravitational field of attraction. So, it changes with height, depth & latitude from location to location in gravitational field. Outside this gravitational field, the same mass body becomes weightless.

Use a balance instead of a scale. It will measure mass instead of weight, because both the reference masses and the body being measured contain g on both sides of the equation. Take a balance to the moon, and it will still measure the same mass. If you need to measure mass without using a gravitational field of any kind, you can measure the inertia as it responds to a known force. A practical way to do this, is to vibrate it on a spring of known stiffness (k) and measure the period of vibration (T). Using T=2*pi*sqrt(m/k), and solving for m, you can determine the mass. And that is how it is done on the International Space Station.
