Physics
Unit 7: Energy
Big Idea:
It’s all about energy! If you want to move something, speed something up, make a light shine, type on your computer, listen to music on your I-Pod, shoot a basket, or anything at all you must transfer energy to do it. Energy comes in many different forms but is never created nor destroyed.
Learning Targets:
At the end of this unit you should be able to truthfully say:
1)I can represent energy relationships using graphs, tables and in writing.
2)I can apply and test mathematical formulas related to energy and motion.
3)I can apply the concepts of work, power and efficiency to describe energy transfers in mechanical systems.
4)I can explain and describe the motion of objects and real-life phenomena using conservation of energy.
5)I can design and conduct experiments or investigations involving conservation of energy and report the results in tables, graphs and writing.
6)I can explain the relationships and connections between matter and energy in a variety of systems, both living and non-living.
7)I can compare the energy released through nuclear reactions (decay, fusion & fission) and the energy released through chemical processes.
Critical Vocabulary:
Energy, Potential Energy, Kinetic Energy, Nuclear Energy, Mechanical Energy, Conservation, Work, Power, Machine, Simple Machine, Lever, Pulley, Inclined Plane, Wheel & Axle, Wedge, Screw, Efficiency, Mechanical Advantage

- Items in Bold will be turned in for a numerical grade. Items in Italics are expected to be in your notebook that you will turn in at the end of the semester.
- There will be lecture days throughout the unit; if you are absent on a lecture day, you will have access to thenotes on my web site and must discuss the information with me before or after school.
