  6. 12. the speed of something in a given direction.
  7. 13. a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
  8. 15. internationally known by the abbreviation SI is the modern form of the metric system and the world's most widely used .
  9. 16. of Conversation of Momentum in an isolated system the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied.
  10. 18. an area of open land, especially one planted with crops or pasture, typically bounded by hedges or fences.
  11. 19. 3rd for every action (force) in nature there is an equal and opposite reaction.
  12. 22. the degree of compactness of a substance.
  13. 23. resistance air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air.
  14. 24. mental or moral strength or power.
  15. 26. 1st every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
  16. 27. a substance made up of various types of particles that occupies physical space and has inertia.
  17. 28. is the quantity of motion of a moving body, measured as a product of its mass and velocity.
  18. 29. firm and stable in shape; not liquid or fluid.
Down
  1. 1. a vehicle's capacity to gain speed within a short time.
  2. 4. an open-meshed fabric twisted, knotted, or woven together at regular intervals
  3. 6. the action or process of moving or being moved.
  4. 7. plot or trace on a graph.
  5. 8. Acceleration the acceleration of a body traversing a circular path. Because velocity is a vector quantity
  6. 9. the rate at which someone or something is able to move or operate.
  7. 10. has the ability to do work.
  8. 14. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
  9. 17. Fall downward movement under the force of gravity only.
  10. 20. level of quality or attainment.
  11. 21. the moving of something from its place or position.
  12. 22. facts and statistics collected together for reference or analysis.
  13. 25. Velocity the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
