Answer

I understand that

Gravity always pulls objects such as a desk, book or person down. Friction, however, doesn't pull objects down. ... Instead friction occurs when something like a machine or individual pulls a sliding object in the opposite direction of another object.

I realize that

With gravity being lower, the force of friction at the contact point is reduced, while the force forward is still the same.

I need to learn about

Gravity and Friction and how they affect the people and object inside the Earth.
