Across
  1. 4. The ability to do work (the use of force to move an object over a distance)
  2. 5. The energy of a particle (or system of particles) derived from position, or condition, rather than motion
  3. 8. The sum of all forces acting on an object. If moving in opposite direction subtract. If moving in the same direction add.
  4. 12. Speed in a given direction
  5. 13. Energy that matter due to its motion
  6. 14. Force must be exerted and there must be motion or discplacement in the direction of the force
  7. 16. State in which one object's distance from another is changing
  8. 17. Always paired with a reaction force
  9. 19. A place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a _____
  10. 22. A substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move
  11. 23. Scientific term used to describe the density and type of atoms in any given object.
  12. 25. Forces acting in opposite directions on an object, and equal in size. When the forces on object are balanced, the object stays still or continues to move at the same speed and in the same direction.
Down
  1. 1. Attractive force between objects; the force that moves objects downhill
  2. 2. The rate of change in distance with respect to time
  3. 3. Always paired with an action force
  4. 6. For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the foe that the second object exerts on the first, but in the opposite direction
  5. 7. A unit of force that will accelerate one kilogram of mass one meter per second squared. Newtons measure force
  6. 9. The force acting on an object that is moving through air flowing in the opposite direction. The air resists the objects movements, slowing it down
  7. 10. The change in motion of an object due to an unbalanced force is proportional to the magnitude of the force, in the same direction as the force, and inversely proportional to the mass of the object.
  8. 11. An object at rest stays at rest, and on object in motion stays in motion with the same speed and same direction, unless acted upon by an unbalanced force
  9. 15. Forces that do not act in opposite directions on an object and are/or are unequal in size.
  10. 18. A mechanical contact force. It is generated by the interaction and contact of a solid body with a fluid.
  11. 20. Force that 2 suraces exert on each other when they rub against each other
  12. 21. The rate at which velocity changes
  13. 24. To push or pull exerted on an object resulting from the object's interaction with another object
