  1. 3. is a type of friction force that acts on objects that are not moving
  2. 4. is a type of friction force that opposes the motion of an object through a fluid
  3. 6. this is a measure of inertia of an object and depends on the amount of matter the object contains
  4. 13. this is an Italian scientist that experimented with rolling balls down a wooden ramp and studied how gravity produces constant acceleration
  5. 14. this is the type of force gravity is
  6. 16. this is a scientist that published a book that introduced laws of motion
  7. 17. this is a Greek scientists and philosopher that made many scientific discoveries but was not always correct
  8. 20. these are forces that combine to produce a net force of zero
  9. 21. is a force that opposes the motion of objects that touch as they move past each other
  10. 22. is a type of nuclear force that is a powerful force of attraction that acts only on the neutrons and protons in the nucleus of an atom
  11. 23. this is what force is measured in
Down
  1. 1. this is the force of gravity acting on an object
  2. 2. is a universal force that is associated with charged particles
  3. 5. these are forces that result in the net forces acting on an object does not equal zero
  4. 7. is a type of friction force that opposes the direction of motion of an object as it slides over a surface
  5. 8. this is the tendency of an object to resist a change in its motion
  6. 9. is a force that acts between any two masses
  7. 10. is a push or a pull that acts on an object
  8. 11. which law of motion states the acceleration of an object is equal to the net force on it divided by the object's mass
  9. 12. which law of motion states whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object
  10. 15. is the product of an object's mass and its velocity
  11. 16. is the overall force acting on an object after all the forces are combined
  12. 18. is a type of friction force that acts on rolling objects
  13. 19. which law of motion states that an object does not change as long as the net force acting on the object is zero
  14. 24. is a type of nuclear force that is an attractive force that acts only over a short range
