In science, a theory is a synthesis of a large body of well-tested knowledge. Science, art, and religion do not contradict one another because all three have different domains. An object in mechanical equilibrium is an object that has no acceleration, is at rest, and/or moving with constant velocity. The rock hits the floor exactly below the midpoint of the ceiling. Inside the storage compartment, a rock is dropped from the midpoint of the ceiling and strikes the. 5) observe this because railroad trains always have forces that oppose their motion.

If the string breaks, the tendency of the rock is to follow a straight-line. While an object near the earth"s surface is in free fall, its velocity increases.
