SCI 1901E - Energy
Chapter Objectives - Chapter 2: Energy Mechanics
Lesson notes:
The lesson introduces a number of key concepts and terms that will be used throughout the entire course. These terms provide the vocabulary necessary to discuss the physical process involved in energy production and use. Appendix B and the back inside cover of the text contain conversion factors that may be useful in problems.
Objectives:
1. Be able to state the forms of mechanical energy.
2. Be able to define displacement, velocity and acceleration, and explain the difference between velocity and speed.
3. Be able to recognize and apply the relationship between force, mass and acceleration as defined by Newton's 2nd Law.
4. Be able to state and use the concept of work and its relationship to energy.
5. Be able to state and use the concept of power
Vocabulary:
SI units
kinetic energy
potential energy
thermal energy
energy conversion process

Additional source of information:
A very nice short biography of Issac Newton is provided by Richard Westfall.
The National Institute of Standards and Technology maintains a Web site devoted to describing the International System of Units (SI system).
