Answer

Brief Explanations:

Gravity is a non - contact force that acts between objects without them physically touching. Force fields are used to describe non - contact forces as they represent the influence of the force over a region of space. Option A is incorrect as gravity pulls objects together, not pushes them apart. Option B is wrong because gravity is not a type of air resistance. Option C is incorrect since gravity acts between any two objects with mass, not charges.

Answer:

D. Gravity is a noncontact force.
