Two students are discussing gravity. One student says that there is a gravitational attraction between the two of them. The other student thinks this cannot be true, because he cannot feel any gravitational attraction to
the other student. Which student is correct, and why?

The first student is correct, even though the force of gravity between them is not noticeable at all. All masses in the universe have a gravitational force of attraction- we feel the gravitational force of the earth because the earth has a very large amount of mass. The gravitational force between the two students is there, but it is a very very very small amount of force. Just because you can’t feel it doesn’t mean it’s not there. Hope that explanation helps! :)
