  2. Mass versus weight - Wikipedia

    en.wikipedia.org/wiki/Mass_versus_weight

    Though the rubber comprising the balloon has a mass of only a few grams, which might be almost unnoticeable, the rubber still retains all its mass when inflated. Again, unlike the effect that low-gravity environments have on weight, buoyancy does not make a portion of an object's weight vanish; the missing weight is instead being borne by the ...

  3. Mass in general relativity - Wikipedia

    en.wikipedia.org/wiki/Mass_in_general_relativity

    The Bondi mass was introduced (Bondi, 1962) in a paper that studied the loss of mass of physical systems via gravitational radiation. The Bondi mass is also associated with a group of asymptotic symmetries, the BMS group at null infinity. Like the SPI group at spatial infinity, the BMS group at null infinity is infinite-dimensional, and it also ...

  4. Gravity - Wikipedia

    en.wikipedia.org/wiki/Gravity

    In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.

  5. Newton's law of universal gravitation - Wikipedia

    The theorem tells us how different parts of the mass distribution affect the gravitational force measured at a point located a distance r 0 from the center of the mass distribution: [13] The portion of the mass that is located at radii r < r 0 causes the same force at the radius r 0 as if all of the mass enclosed within a sphere of radius r 0 ...

  6. Mass - Wikipedia

    en.wikipedia.org/wiki/Mass

    In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh less than it does on Earth because of the lower gravity, but it would still have the same mass.

  7. Your Poop Can Weigh Up To Four Pounds, But That Doesn't ... - AOL

    Either way, pooping won’t affect your weight in any huge way—even if it does feel like you just dropped 10 pounds. That amazing feeling is more about de-bloating than actual loss of body mass.

  8. Mass in special relativity - Wikipedia

    en.wikipedia.org/wiki/Mass_in_special_relativity

    The term mass in special relativity usually refers to the rest mass of the object, which is the Newtonian mass as measured by an observer moving along with the object. The invariant mass is another name for the rest mass of single particles. The more general invariant mass (calculated with a more complicated formula) loosely corresponds to the ...

    Anxiety disorders — characterized by uneasiness, worry, and fear — can cause various symptoms that affect how you think and behave. This can include changes in appetite (aka your body’s ...
