Work, Energy, and Power: Science Unit 4, Grade 11 (Letters & Devotion)

Description

Work, Energy, and Power is Unit 4 of Algebra-Based Physics: Modeling Matter, Motion, and Energy (Grade 11), the Letters & Devotion Science course, complete in one printable PDF: 9 lessons, the unit check-up and the answer key, 84 pages.

• Work as force times displacement, with angle/component consideration
• Kinetic energy (1/2 mv^2) and gravitational potential energy (mgh)
• Conservation of mechanical energy and energy dissipation as heat/sound/deformation
• The distinction between conditions for momentum conservation (always, isolated system) versus mechanical energy conservation (only without dissipation)
• Power as rate of energy transfer (P = W/t = ΔE/t)
• Experimental verification of conservation of mechanical energy using height and speed measurements
• Application of energy and momentum conservation reasoning to novel multi-stage mechanical systems
• Quality of justification for conservation-law selection in mechanical scenarios
• Real-world energy transformation processes described in technical/informational text

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
