Forces and Newton’s Laws: Science Unit 2, Grade 11 (Letters & Devotion)

Description

Forces and Newton’s Laws is Unit 2 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, 75 pages.

• Free-body diagrams representing forces acting on a single object
• Newton’s first law (inertia) as it applies to motion without a sustaining force
• Newton’s first law applied to scenarios engineered to trigger impetus misconceptions
• The F = ma relationship as a proportional statement linking net force, mass, and acceleration
• The proportional (not merely computational) relationship between force, mass, and acceleration
• Newton’s third law interaction pairs versus balanced forces acting on one object
• Static and kinetic friction and the transition between them, evidenced by measured force and acceleration data
• The distinction between mass (invariant) and weight (dependent on local gravitational field)
• Argumentation defending a Newtonian prediction against an explicitly stated impetus-theory counterclaim

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.
