Across
  1. 6. pair, The action force and the reaction force that occur in an interaction
  2. 7. Fake science that pretends to be real science.
  3. 10. fall, falling under the influence of gravity alone—falling without air resistance.
  4. 11. resistance, The force of friction acting on an object due to its motion in air.
  5. 12. speed, The speed at which the acceleration of a falling object terminates when air resistance balances its weight
  6. 14. Any object that moves through the air or through space under the influence of gravity.
  7. 16. time, The time that one’s feet are off the ground during a vertical jump.
  8. 18. The oval path followed by a satellite. The sum of the distances from any point on the path to two points called foci is a constant. When the foci are together at one-point, the ellipse is a circle. As the foci get farther apart, the ellipse becomes more eccentric
  9. 19. Likes to chase mice
  10. 20. of energy, Energy cannot be created or destroyed; it may be transformed from one form into another, but the total amount of energy never changes.
  11. 22. The quantity of matter in an object. More specifically, a measure of the inertia (or sluggishness) that an object
  12. 23. Flying mammal
  13. 25. Large marsupial
  14. 27. collision, A collision in which colliding objects rebound without lasting deformation or the generation of heat.
  15. 29. force, The combination of all forces that act on an object
  16. 30. A projectile or small celestial body that orbits a larger celestial body
  17. 33. The quantity of space an object occupies.
  18. 34. Mutual action between objects during which each object exerts an equal and opposite force on the other.
  19. 36. Man's best friend
  20. 37. Simply stated, a push or a pull.
Down
  1. 1. being without a support force, as in free fall.
  2. 2. Has a trunk
  3. 3. The speed of an object and specification of its direction of motion.
  4. 4. The percentage of the work put into a machine that is converted into useful work output.
  5. 5. velocity, terminal speed in a given direction, often downward.
  6. 8. The scientific unit of force.
  7. 9. The rate at which velocity changes with time; the change in velocity may be in magnitude or direction or both, and it is usually measured in units of m/s2
  8. 13. A general hypothesis or statement about the relation-ship of natural quantities that has been tested over and over again and has not been contradicted; also known ASA principle
  9. 15. Distance traveled per unit time
  10. 16. An educated guess; a reasonable explanation of an observation or experimental result that is not fully accepted as factual until tested over and over again by experiment.
  11. 17. The curved path followed by a projectile under the influence of constant gravity only.
  12. 21. force, The force that supports an object against gravity, often called the normal force
  13. 24. The resistive force that opposes the motion or attempted motion of an object past another object with which it is in contact, or through a fluid.
  14. 26. An arrow that represents the magnitude and direction of a quantity.
  15. 28. A synthesis of a large body of information that encompasses well-tested and verified hypotheses about certain aspects of the natural world
  16. 31. The force that an object exerts on a supporting surface (or, if suspended, on a supporting string), which is often, but not always, due to the force of gravity
  17. 32. The unit of mass. One kilogram (kg) is the mass of 1 liter (L) of water at 4°C
  18. 35. The property by which objects resist changes in motion.
