This statement is utterly false because weight depends on the gravitational force acting upon mass. In the space ship, there is still gravity acting upon them, but it is so little that they float. The only way something can be weightless in space is if it has no mass. Weight varies depending on where the object is in relation to the Earth (or any large body in the universe). It is true that when the astronauts return to Earth, they will have a greater weight than in outer space because Earth has a stronger gravitational force. And when they were in space, they still had weight, but the gravitational force exerted on their bodies was not enough to keep them from floating. (Check your review, I'm not 100% sure this is correct)
Jawaban
Penjelasan
### Weight is defined as the force exerted by gravity on an object. It is calculated by multiplying the mass of the object by the gravitational acceleration. The formula for weight is $W = mg$, where $W$ is the weight, $m$ is the mass, and $g$ is the gravitational acceleration.
## Step2: Gravity in Space
### In space, gravity still exists, but it is significantly weaker than on Earth. This is because the gravitational force decreases with distance from the Earth. Astronauts in space experience a weaker gravitational force, which is why they appear to float. However, this does not mean they are weightless.
## Step3: Weightlessness in Space
### An object is considered weightless when its weight is zero. This can only happen if the gravitational force acting on the object is zero. In space, the gravitational force is not zero; it is just much weaker than on Earth. Therefore, astronauts are not truly weightless in space.
## Step4: Weight Changes Upon Returning to Earth
### When astronauts return to Earth, they experience a stronger gravitational force compared to space. This results in a higher weight compared to when they were in space. This change in weight demonstrates that astronauts were not weightless in space, but rather had a lower weight due to the weaker gravitational force.
