Final answer:
Mission, vision, readiness, internal strengths, and external threats are inputs in the systems model of change. They define the organization's aspirations and situational context for managing change, while internal and external forces are instrumental in changing a system's motion, requiring energy inputs.
Step-by-step explanation:
In the systems model of change within the context of organizational management, mission, vision, readiness, internal strengths, and external threats represent inputs into the system. The mission and vision guide the direction and ambitions of the organization, readiness pertains to the organization's preparedness for change, internal strengths are the capabilities and resources within the organization that can be leveraged during change, and external threats are the challenges or obstacles posed by the environment outside the organization.
Regarding the process of changes in the motion of a system and Newton's Third Law of Motion, both internal forces and external forces can cause changes. Processes are powered by some input of energy, for which the source can be internal, like chemical energy in a biological system, or external, such as heat from the sun. The system interacts with its environment, receiving energy that enables it to function and change.
