Across
  1. 5. force that produces a nonzero net force and changes an object’s path of motion
  2. 6. the unit of measure for force
  3. 10. force applied on an object by a living person, animal, etc.
  4. 11. another name for drag
  5. 13. force that acts between the protons and neutrons of atoms
  6. 14. caused by repulsion between atoms/molecules as an object is compressed
  7. 15. a push or a pull on one object by another that is touching it
  8. 18. force caused by excess electrical charge
  9. 20. a push or pull on an object
Down
  1. 1. upward force exerted on an object that is submerged in a fluid
  2. 2. supporting force exerted on an object in contact with a surface
  3. 3. a force that one object can apply to another object without touching it
  4. 4. downward force of gravity acting on an object
  5. 7. the overall force on an object when all the forces acting on it are added together
  6. 8. equal forces acting in opposite directions creating a balance
  7. 9. opposing force caused by irregularities and chemical bonds between surfaces moving past each other
  8. 12. force due to charged objects in a magnetic field
  9. 16. caused by the attraction of atoms/molecules within a stretched rope or string
  10. 17. caused by an object pushing air out of the way
  11. 19. force that acts at a right angle to the direction of motion of an object through air
