  1. 1. Force- forces that produce a nonzero net force, which changes an object's motion
  2. 5. Force- equal forces acting on an object in opposite directions
  3. 9. Force- A force exerted toward the center of a curved path
  4. 11. Force-A push or pull on one object by another that is touching it
  5. 14. Force- The upward force that is applied to objects when they exert a force on a surface
  6. 15. force that one surface exerts on another when the two surfaces rub against each other
  7. 16. amount of matter in an object
  8. 17. a push or pull exerted on an object
Down
  1. 2. When the net force of an object is zero
  2. 3. Force- A force that one object can apply to another without physically touching
  3. 4. The tendency of an object to resist any change in its motion
  4. 6. Resistance- Friction acting upon an object moving through the air
  5. 7. force of gravity on an object at the surface of the planet
  6. 8. Velocity-The maximum speed an object will reach when free-falling through a substance, such as air
  7. 10. Force- the overall force on an object when all the individual forces acting on it are added together
  8. 12. force that pulls objects toward each other
  9. 13. Fall- the motion of a falling object when the only force acting on it is gravity
  10. 14. unit of measurement that equals the force required to accelerate 1 kilogram of mass at 1 meter per second, per second
