🔬 Grade 8 • 🚀 Forces, Motion, and Newton's Laws

Forces, Motion, and Newton's Laws

Use Newton's laws, force diagrams, and motion evidence to explain inertia, acceleration, gravity, and action-reaction pairs in real systems.

📋 What You'll Learn

  1. 1 Explain motion changes using Newton's first, second, and third laws
  2. 2 Use net force and mass to predict changes in acceleration
  3. 3 Interpret interactions such as collisions, pushes, pulls, and gravity with evidence
  4. 4 Apply force-and-motion reasoning to engineered solutions and real situations
