Providing that it does not collide with another object, what is the most likely reason that an object moving through space would change velocity?

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).
