Question

it was found that the astronauts in a space ship had no difficulty in swallowing food even if they were upside down. Can you explain why? Can you swallow food when you are upside down on Earth? Explain your answer. ​

Answer 1

These happens because

First of all they are in space and as you told they are upside down means there is very less or no gravitational force.

As there the gravitational force is so week they don't require much energy to swallow the food as compared to earth.

hence, the Astronot in space craft had no difficulties in swallowing food.
