Question

question 20 of 25
why are force fields necessary to describe gravity?
a. gravity can only push objects apart.
b. gravity is a type of air resistance.
c. gravity acts between any two objects with charges.
d. gravity is a noncontact force.

Explanation:

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.
