πŸ“š Quick Study Guide

  • 🍎 Inertia is an object's tendency to resist changes in its state of motion.
  • πŸš— An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a force.
  • ⚽ The more massive an object, the more inertia it has. A bowling ball has more inertia than a soccer ball.
  • πŸ›Ή Examples include: a soccer ball staying still until kicked, a car continuing to move even after you take your foot off the gas, and shaking water off your hands.
  • πŸ“ Newton's First Law of Motion is also known as the Law of Inertia.
