Across
  1. 5. a property by which objects resist change in motion
  2. 6. friction acers once an object is in motion, this type of friction will resist the motion
  3. 7. energy is what matter possesses due to its position-Gravitational PE=mgb
  4. 9. What is a projectile or small celestial body that orbits a larger celestial body
  5. 11. velocity is speed in a given direction (often downwards)
  6. 12. a______ equilibrium is the state of balance between opposing forces where the forward and reverse processes occur at the same time.
  7. 13. speed that a projectile, space probe, or similar object must reach to escape the gravitational influence of earth
  8. 14. Inertia in motion, given by the product of the mass of an object and its velocity
  9. 16. The product of the force acting on an object and the time during which it acts
  10. 18. _____is the falling only under the influence of gravity, falling without air resistance
  11. 20. friction is when an object is at rest and another force attempts to move it, _____friction will attempt to prevent it
  12. 22. The rate at which velocity changes with time; the change on velocity may be in magnitude or direction or both usually measured in MLS
  13. 24. a________ Equilibrium is state where the net force on an object or system is ZERO
  14. 25. Pair an action and reaction pair of forces that occur in an interaction
Down
  1. 1. energy a consequence of an object in motion
  2. 2. an resistive force that opposes the motion or attempted motion of an abject past another with which it is in contact, or through a fluid
  3. 3. a______ Equilibrium is a state where an object or system is at rest and all forces acting on it are balanced
  4. 4. speed is where the acceleration of a falling object terminates when air resistance balances its weight
  5. 7. any object that is projected by some means and continues its motion by its own inertia
  6. 8. resistance is the force that is experienced as an object pushes air molecules out of the way
  7. 10. a______ quantity is a description requires both magnitude and direction
  8. 15. is the quantity of matter in an object.
  9. 16. Collison in which the colliding objects becomes distorted, generate heat, and possibly stick togather
  10. 17. a force that an object exerts on a supporting surface.
  11. 19. What velocity takes the total distance traveled divided by the time elapsed?
  12. 21. mutual action between objects during which each object exerts an equal and opposite force on the other
  13. 23. collision in which colliding objects rebound without lasting deformation or the generation of heat
