1. What is work: When a force is applied on a body, it may or may not move depending upon the magnitude of the force and mass of the body. For example, if one tries to push a massive rock, it will not move. The person trying to push gets tired and we will concede that he did do work, albeit unsuccessfully. However, in study of mechanics, work is said to have been done by the force on the body only if the body moves. No work is done if the body does not move.

2. Magnitude of work: The magnitude of work done by the force F in causing a displacement s is defined as the product of the displacement and component of the force in the direction of the displacement.

Since displacement s and force F are vectors, by the definition of scalar (or dot) product, work W can also be expressed as W = s . F

Work done is a scalar quantity.

3. Units of Work: ...

Review the e-text and other readings, and pick out five terms or concepts. At least one term must be included from each week's learning (You will need to look ahead for your term from Week 5). "Terms" can be either general or specific.

Write an essay where you define and explain these five terms and apply them to a critique of management in either a past or present workplace or life experience. Focus should be placed on how to improve the management in your company or life, using what you've learned. For example, you might choose "employee buy-in to the BCP" as a concept. Then, you could write about how your organization's decision-making methods could be improved based on research, text, lecture, etc. material on this topic.

The Final Exam is to be
· in APA format (If you were weak in this, by now you should be much better because you've taken advantage of your teammates' knowledge),
· in MS Word with a title page,
· an Executive Summary,
· an introductory paragraph,
· a discussion portion with graphics and/or charts (If you didn't know how to do this, by now you should have learned from a team member),
· a conclusion paragraph,
· and a reference page with at least four references (minimum of three references must come from the articles in the UOP Library).

Week 1 - Ethical and cultural considerations
Week 2 - Communication and teamwork
Week 3 - Business continuity or crisis management
Week 4 - Risk Analysis or Training employees for Disasters
Week 5 - Disaster preparedness or exposure to disasters:
