Across
  1. 5. - When multiple forces interact the net force is the mass of obj X the resulting velocity
  2. 7. forces within an atom that control the Particles to keep it together
  3. 10. friction force you need to overcome to get a stationary object moving F_{s} =
  4. 11. If there is no ______________ the total net force = 0
  5. 13. the force that force that keeps electrons in orbit and evenly distributed
  6. 16. the speed a falling object has where the air resistance is equal to the accelleration.
  7. 17. friction -friction between moving objects
  8. 19. friction- friction that slows the movement of a round moving object
  9. 20. -for every action there is an equal but opposite reaction.
  10. 22. is the force down an object has due to gravity. U=MX A
  11. 23. friction- friction that impedes the Start of motion (the object is still)
  12. 24. the force exerted when 2 obj. hit. (Re)
  13. 25. Acceleration of falling objects A(g) is Constant (9.8m/s or 32 ft/s)
Down
  1. 1. friction- friction between moving objects and the air or water around them
  2. 2. Mass energy if you have enough speed E = m * c ^ 2
  3. 3. holds nucleus together slowing decay.
  4. 4. a force between 2 objects that are touching that opposes motion
  5. 6. -sum of positive and negative forces on an
  6. 8. forces
  7. 9. ( first law of motion )an object at rest will stay at rest unless acted on by a force. And an object in motion will stay in motion unless acted by a force. on
  8. 12. A natural force between positively charged and negatively Charged particles.
  9. 13. friction-friction between a moving object and the surface its moving on
  10. 14. a force between 2 objects whose Strength depends on the mass of the objects and their distance. f = G * (m_{1}*m_{2})/(r ^ 2)
  11. 15. a unit of measure for force = Kg/m/82
  12. 18. a push or pull that acts on an object.
  13. 21. the force of any moving object. (the force is related to mass of the object)
