Three friends climb a mountain and are standing at the top after their long hike. The friends want to know who is feeling the most pull from Earth's gravity. How can this be determined?

Question

by finding out which person has the most volume, because they will have more gravitational pull
by finding out which person has the most mass, because they will have more gravitational pull
by finding out which person is stronger, because they will have less gravitational pull
by finding out which person climb the mountain faster, because they will have less gravitational pull

Answer 1

To determine who is feeling the most pull from Earth's gravity, the correct approach is:

by finding out which person has the most mass, because they will have more gravitational pull.

Gravitational force depends on the mass of an object, as described by Newton's law of universal gravitation. The more mass a person has, the greater the gravitational force acting on them. Therefore, the friend with the most mass will experience the strongest pull from Earth's gravity, regardless of volume, strength, or climbing speed.
