C. Contact forces require objects to physically touch, while action-at-a-distance forces do not.
D Action-at-a-distance forces require objects to physically touch, while contact forces do not.

Answer 1

Answer:

A

Contact forces are forces that require the actual contact (touching) of two pieces of matter. ... A field force is a force that works at a distance. No touching is required. Gravity is a good example of a field force, because it works whether or not an object is touching something or touching nothing at all.
