Jennie observes her brother playing pool and has a theory that the potential energy in the pool stick is transformed into kinetic energy when he hits the ball.
Which explains how she can prove her theory?


A
She could measure the potential energy in the motionless ball on the pool table, and she could measure the potential energy of the pool stick as it moves to strike the ball. These total of these two measurements will be equal to the kinetic energy in the pool ball as it moves, and this proves there was a transformation of energy.
B
She could measure the potential energy when the pool stick is pulled back to strike the pool ball, and then she could measure the kinetic energy in the pool stick as it moves to strike the ball. The potential energy in the pool stick and the kinetic energy in the pool stick should be equal, proving there was a transformation of energy.
C
She could measure the potential energy when the pool stick is pulled back before moving to strike the pool ball, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of kinetic energy and potential energy to prove there was a transformation of potential energy to kinetic energy.
D
She could measure the potential energy of the pool ball when it was sitting on the table, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of potential energy in the motionless ball and kinetic energy in the ball after the stick strikes it to prove there was a transformation of potential energy to kinetic energy.

Sample occupations include:

Foreign Service Officer

Diplomatic Officer

Consular Officer

Ambassador

Diplomatic Courier

People who work in the Planning pathway develop long- and short-term land use plans to provide for growth and revitalization of urban, suburban, and rural communities, while helping local officials make decisions concerning social, economic, and environmental issues.

Sample occupations include:

Planner

Census Enumerator

Census Clerk

Federal Aid Coordinator

Economic Development Coordinator

Chief of Vital Statistics

Revenue and Taxation

People who work in the Revenue and Taxation pathway ensure that governments obtain revenue from businesses and citizens by collecting audits, monitoring taxes payable and collecting overdue tax dollars.

Sample occupations include:

Tax Examiner

Tax Clerk

Revenue Agent

Internal Revenue Investigator

Assessor

Auditor

Regulation

People who work in the Regulation pathway will typically possess a body of technical knowledge about an industry, the environment, or technology. This –coupled with a knowledge of related laws, rules, and regulatory systems –permit regulators to protect our health, safety, and environment as well as ensure the integrity of our financial, transportation, and public utility industries.

Sample occupations include:

Investigator/ Examiner

Code Inspector

Bank Examiner

Election Supervisor

Child Support Officer

Cargo Inspector

Border Inspector

Aviation Safety Officer

Public Management and Administration

Government agencies and public corporations and trusts have specific and rigorous standards for the stewardship of public resources. Public management careers will require technical skills related to budgeting, personnel management, procurement or other activities, and specific knowledge of the regulations and other policies that govern public management.

Sample occupations include:

Court Administrator or Clerk

City or County Clerk

City Council Member

City Manager

Purchasing Manager

5] Set goals effectively

Goals are the basis of an effective performance management process. There are two key elements to consider when developing goals. First, are goals written clearly and objectively? Second, are they directly contributing to the achievement of business strategy?

Typically, the process begins with departmental managers setting goals for their departments, based upon organization-wide goals, which support the general business strategy. Making departmental goals accessible to all managers ensures there is no overlap, reduces conflict, and allows members of different departments to see where they support each other and ensure they are not working at cross purposes. Each manager in turn shares the overall goals with his/her department and meets with employees to identify individual performance goals and plans.

When setting goals, key job expectations and responsibilities should act as the main guide and reference. Goals should be set that not only address what is expected, but also how it will be achieved. For example, the "what" covers quality or quantity expected, deadlines to be met, cost to deliver, etc. The "how" refers to the behavior demonstrated to achieve outcomes, for example, focus on customer service. In addition, some organizations choose to include competencies within performance expectations, to reinforce the link to business strategy, vision and mission.

An accepted framework to use to help write effective goals is SMART
