What is your weight in zero gravity?
The force is not gravitational. Typically, it is a contact force and not uniform across the mass of the body. If the body is placed on the scales in a lift (an elevator) in free fall in pure uniform gravity, the scale would read zero, and the body said to be weightless i.e. its weight2 = 0.
How does weight work with gravity?
Weight refers to the gravity force of planets and other bodies in the Universe, and the effect that this has on objects. This means that for a given gravitational field strength, the greater the mass of the object, the greater its weight. Weight is a non-contact force because gravity exerts its force through a field.
How does the body work in zero gravity?
In zero-G, muscles atrophy quickly, because the body perceives it does not need them. The muscles used to fight gravity –like those in the calves and spine, which maintain posture– can lose around 20 per cent of their mass if you don’t use them. Muscle mass can vanish at a rate as high as 5\% a week.
How do astronauts weigh themselves in the state of weightlessness?
In place of a scale, NASA astronauts use something called a Space Linear Acceleration Mass Measurement Device (SLAMMD) to “weigh” themselves. Once they mount the pogo stick-like contraption it moves them a meter using a built-in spring. Measuring weight isn’t the only everyday activity that’s complicated in space.
Is weight dependent on gravity?
That is, the weight of an object is determined by the pull of gravity on it. Thus, an object’s physical weight may change from place to place: if a body weighs 54 kg on Earth, its weight will be just over 9 kg on the Moon, since the Earth’s gravitational force is six times stronger than the Moon’s.
Does mass have weight without gravity?
Weight is mass times acceleration due to gravity(W= mg). In essence it is the force with which a body is pulled downwards(towards the Earth). In absence of gravity, weight is zero.
