📦 Save with the Gravity Unit Bundle: Get every gravity resource I sell — quizzes, slide decks, labs, crosswords, warmups, the test, and the escape room — bundled for $48.75. Get the Physics Gravity Unit Bundle — NGSS Grades 9-12 → Students explore how mass, distance, and velocity affect gravitational force and orbital motion using the free PhET Gravity and Orbits simulation. They manipulate star and planet mass sliders, adjust velocity arrows mid-orbit, and observe changes to orbital paths — building intuition about Fg = Gm1m2/d2 through direct experimentation. What's Included: • Simulation activity worksheet with 14 guided tasks and analysis questions • Teacher notes with answer key and pacing guide • Print-ready digital resource + editable Word formats Works on any laptop or Chromdigital resource. No lab equipment needed. Perfect for sub plans. Designed for Grades 9-12 physics. NGSS-aligned. 45-60 minutes. 📦 Get the complete Gravity unit This resource is part of the Gravity Unit Bundle — all lessons, labs, assessments, and review materials for the full unit.
