Across
  1. 2. Force A force that acts on an object moving in a circular path, directed toward the center around which the object is moving.
  2. 4. The force transmitted through a string, rope, cable, or any other type of flexible connector.
  3. 7. Third Law For every action, there is an equal and opposite reaction.
  4. 9. The force that tends to shorten or squeeze something.
  5. 10. The force that attracts objects toward the center of the Earth (or any other celestial body).
  6. 14. of Energy Energy cannot be created or destroyed, only transferred or converted from one form to another.
  7. 17. The product of an object's mass and velocity.
  8. 19. The state of a body at rest or in uniform motion, with all forces acting on it balanced.
  9. 20. Energy The energy an object possesses due to its motion.
  10. 21. The rate at which velocity changes over time.
  11. 22. The property of a material that returns to its original shape after being deformed.
  12. 24. Machine A basic mechanical device for applying force.
  13. 26. A simple machine consisting of a wheel over which a rope or chain is pulled.
  14. 27. The change in momentum of an object, resulting from a force applied over time.
  15. 28. Plane A flat surface set at an angle to the horizontal.
  16. 29. A force that opposes motion between two surfaces in contact.
Down
  1. 1. The amount of matter in an object.
  2. 3. A push or pull on an object.
  3. 5. First Law (Law of Inertia) 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 an external force.
  4. 6. The capacity to do work.
  5. 8. The force exerted on an object due to gravity.
  6. 11. Energy The stored energy of an object based on its position or state.
  7. 12. Speed in a given direction.
  8. 13. The product of the force applied to an object and the distance over which it moves.
  9. 15. The tendency of an object to resist changes in its state of motion.
  10. 16. Second Law The force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).
  11. 18. Advantage The ratio of the force exerted by a machine to the force applied to it.
  12. 23. An event in which two or more bodies exert forces on each other for a relatively short time.
  13. 25. The rate at which work is done or energy is transferred.
