Across
  1. 2. A push or pull applied over time that changes momentum.
  2. 6. When objects affect each other (push, pull, or collide).
  3. 9. A change in position; movement.
  4. 12. (of momentum) Momentum stays the same in a closed system.
  5. 13. The size or amount of something (the number value).
  6. 14. A quantity that has both size and direction.
  7. 17. The way something is moving or pointing.
  8. 18. (collision) A collision where objects bounce and kinetic energy is not lost.
  9. 19. When two objects are touching.
  10. 20. The amount of matter in an object.
Down
  1. 1. Speed in a specific direction.
  2. 3. To become different; in physics, a difference in motion or momentum.
  3. 4. The amount of motion an object has (mass × velocity).
  4. 5. When two objects hit each other.
  5. 7. To bounce back after hitting something.
  6. 8. (collision) A collision where objects stick together or lose kinetic energy.
  7. 10. How long something lasts or how long motion takes.
  8. 11. A push or a pull on an object.
  9. 15. When something moves from one object to another (like momentum).
  10. 16. A group of objects being studied together.
