Short Writing for the Unit (Like a chapter from a book)
The total energy of the universe is constant; however, the total amount of energy available for useful transformation is almost always decreasing. Energy can be converted from one form to another and move from one system to another. Transformation of energy usually produces heat that spreads to cooler places by radiation, convection, or conduction. Energy can be classified as potential or kinetic energy. Potential energy is stored energy and includes chemical, gravitational, electrostatic, elastic and nuclear. Kinetic energy is the energy of motion.
STANDARD 4: STUDENTS WILL UNDERSTAND TRANSFER AND CONSERVATION OF ENERGY.
Objective 1: Determine kinetic and potential energy in a system.
Objective 2: Describe conservation of energy in terms of systems.
Objective 3: Describe common energy transformation and the effect on availability of energy.

Unit 8 Notes: Work, Energy, and Power
Notes from class:
Online Help:
- Check out the Physics Files page for PowerPoint notes from class.
- Energy--
- Kinetic Energy = 1/2 m*v²
- Gravitational Energy = mgh
- Elastic Energy = 1/2 k*x²
- Dissipated Energy = Work done by friction or other forces.
- Also, Dissipated energy can be found by finding the difference between the initial and final energies.
- Hooke's Law: F=kx (k=spring constant--the slope of F vs. x graph, x=displacement of spring from rest position)
- Physics eBooks can be found HERE. Look for unit 7.
Online Help:
- The Physics Classroom review of Work, Energy, & Power
- Khan Academy -- Physics -- Work & Energy (you can skip the Mechanical Advantage section if you wish)
