Across
  1. 3. A force that opposes motion, such as friction or air resistance.
  2. 6. A push or pull that can change an object’s motion, speed, direction, or shape.
  3. 7. The total length of the path an object travels, regardless of direction.
  4. 8. The speed of an object in a specific direction.
  5. 9. Force Forces acting on an object that do not cancel out, causing a change in motion (acceleration).
  6. 12. Force Forces acting on an object that are equal in size and opposite in direction, resulting in no change in motion.
  7. 13. The tendency of an object to resist changes in its state of motion; objects with more mass have more inertia.

  1. 1. The SI unit of force; one newton is the force required to accelerate a 1-kilogram mass by 1 meter per second squared.
  2. 2. The rate at which an object’s velocity changes over time, including changes in speed or direction.
  3. 4. How fast an object is moving; calculated as distance divided by time.
  4. 5. A force of attraction between objects with mass; on Earth, it pulls objects toward the center of the planet.
  5. 8. A quantity that has both magnitude (size) and direction.
  6. 10. Force The combined effect of all forces acting on an object, taking direction into account.
  7. 11. The straight-line distance and direction from an object’s starting point to its ending point.
