Help Physics finding M Mass

If we are just floating in space without any influence in gravity then, like I said, we often can't calculate the mass. But, if we are floating in space orbiting something like, say, the sun, then you can use Kepler's third law to calculate our mass in space (T^2 /r^3 = 4Pi^2 /GM). This method is only one of the ways to calculate for mass. You can also use M = 4 π^2 a^3 / (G T^2 ) where n = pi, T = revolution time, G = universal gravitational constant (6.67384 × 10^-11 m3 kg^-1 s^-2)



In common terms, mass and weight can be interchangeable so it is understandable why there is confusion. In science and engineering, Mass isn't your weight, per se, but the 'amount' of matter in your body. Weight is the effect of gravity on you. You weigh less on the moon because of lower gravity but the amount of stuff in you remains the same.

So you mean something like m=V(amu)? When you say the amount of matter, are you referring to getting the total mass of each particle in an object?

What I am trying to say boss is that, is there any equation to calculate our mass in a vacuum space? We can't use m=N/a for sure, since N = weight. And to get weight we use the formula weight = ma... confusing since m=? Then if your saying that if I weight 10kg on Earth, I would still weight 10kg on say, Jupiter? I'm pretty sure that the acceleration due to gravity in Jupiter isn't 9.8m/s squared. Or am I wrong? I know our mass is constant, but how what equation or formula do we use to get our true mass.

Your error here is that you assume that your weight is constant everywhere. Remove that thought and you will see that F=ma is valid on all the places that you mentioned.

Forgot the formula. Wla pud ako book ani. Look up true mass. I-derive nimo ang mass using the volume of the object. Unya naa pa pud to mass sa air.

okay thank you sir

Is mass constant or not?

Mass is equal to the object's measure of energy content.

Mass is constant when there is no mass added or removed or no energy transferred.

To move an object from rest you are doing work. Energy is transferred to the object, therefore the object's mass has changed. Hardly noticeable though.

Imagine the energy transferred using the speed of light.

E=mc^2

Imagine the increase in mass.

I did some research on the origins of Mass, or what gives everything it's mass. Right now they are still researching for this since they just discovered the Higgs.

Unya na-solve na nimo ang formula, TS? Abot na man ka Higgs mechanism ug mass generation.

Dili pa gihapon, kay Higgs didn't provide 100% of our mass, I think they are waiting for another particle "Graviton" maybe.... thing is it's very difficult for this particle to be detected as it can move from one dimension to another... if discovered however, this will move gravity as the strongest of all forces of nature....

what do you know about the nuclear force?

what do you know about the nuclear force?

As far as I know about nuclear force is that there are 2 in the standard model, the strong and the weak nuclear force, i'm not really that interested in those two compared to gravity...
