Across
  1. 5. the distance an object travels per unit not time
  2. 7. the rate which velocity changes
  3. 8. the overall force on an object when all the individual forces acting on it are added together
  4. 10. stored energy that results from the position or shape of an object
  5. 12. speed in a given direction
  6. 13. the force that one surface exerts on another when the two surfaces rub against each other
  7. 15. when these two forces are equal, the object stops accelerating and reaches its maximum Velocity
  8. 16. the force of gravity on an object at the surface of a planet
  9. 18. Equals forces acting on an object in opposite directions
  10. 19. the force that pulls objects towards each other
Down
  1. 1. the orbit of the space shuttle around earth is an example of projectile motion
  2. 2. Forces that produce a nonzero net force, which changes an objects motion
  3. 3. the amount of inertia depends on this
  4. 4. a unit of measure that equals the force required to accelerate 1 kilogram of mass 1 meter per second per second
  5. 6. Energy that an object has due to its motion
  6. 9. when gravity is the only force acting on an object, the object is said to be in free fall
  7. 11. the tendency of an object to resist any change in its motion
  8. 14. the product of an objects mass and velocity
  9. 17. the state in which one objects distance from another is changing
