weight and mass are the same thing

• No - mass is a function of gravity and weight is the atoms and molecules that make up the object

• No - weight is a function of gravity and mass is the atoms and molecules that make up the object

• Yes - they are both the same

• Maybe - it depends on the flux capacitor

If the image were transported to the space station the gravitational attraction between the 2 ends would

• change because you are in freefall

• not change because the mass and distance are the same

• change because the weight would change

• not change because of microgravity
