In space, weightlessness occurs because there is no gravity acting on objects. As a result, objects and astronauts float freely without feeling the sensation of weight. This is different from mass, which remains constant regardless of location.
An example is when an object is moved from one location to another where the gravitational pull is different. Weight is dependent on gravity, so a change in gravity would cause the weight of the object to change while its mass remains the same.
Weight depends on mass and the acceleration due to gravity, while volume is a measure of the space occupied by an object. The weight of an object may change depending on the mass and the gravitational pull, but the volume of the object remains constant as long as its shape and size do not change.
Space itself does not have mass or weight, as it is a vacuum with no material substance. Mass is a property of matter, while weight is the force of gravity acting on that mass. Objects in space have mass and weight because they are affected by the gravitational pull of celestial bodies like planets or stars.
Mass does not change with location because it is a measure of the amount of matter in an object. However, weight does change with location because it is the measure of the gravitational force acting on an object. So, an object will weigh less where gravity is weaker, like in outer space.
To calculate total weight change, you need to subtract the initial weight from the final weight. The formula is: Total weight change = Final weight - Initial weight
Yes
Yes
Because weight is based on gravity, and gravity changes throughout space.
The mass of an astronaut does not change when she is visiting the International Space Station. Mass is a property that does not change, but the weight of a person does change in space.
Your weight does not technically change when you go into space, as weight is the force exerted on an object due to gravity. However, in space your gravitational force is reduced (you are in a state of freefall), so you experience the sensation of weightlessness.
Your weight Oxygen level
the weight reduces due to change in gravity but mass remains constant
Yes it does! Because of the gravity on earth we get pulled down, but in space there ain't anything like this, so we all weight 0kg
To calculate weight in space, you would use the formula: Weight in space = Weight on Earth x (gravitational pull of space / gravitational pull of Earth). Since gravitational pull in space is typically much lower than on Earth (about 0.17 times that of Earth), your weight in space would be significantly less. Keep in mind this calculation assumes a constant gravitational pull throughout the region of space you are in.
The astronaut's mass remains the same in space as it does on Earth. However, their weight (the force of gravity acting on them) will decrease in space compared to on Earth due to the absence of gravity.
Because there is almost no gravity in space. When a person is in orbit just outside of earth, the outward acceleration will cancel out the force of gravity, giving a person zero weight.
Its mass is the same(ignoring spent fuel) but the weight is a result of the gravitational pull, which is different in space. Actually the space shuttle never gets far enough from the earth for it's weight to change. The reason it seems weightless is because it is in free-fall.
