Across
  1. 4. – the amount of matter in an object
  2. 5. 1st Law – states that an object at rest will stay at rest unless it is acted upon by an unbalanced force.
  3. 6. forces – work against motion
  4. 10. Force – forces that are opposite in direction and equal in size, cause no change in motion, and the net force equals 0.
  5. 11. 3rd Law - states that forces occur as equal and opposite pairs.
  6. 13. - is the transfer of energy when an applied force moves an object over a distance.
  7. 14. – the force due to gravity-Equal to the product of the object's mass and the acceleration of gravity (w = mg).
  8. 15. - a measure of speed in a given direction
  9. 17. Force - forces that are not opposite and equal.
  10. 18. – an action that can change the motion of an object.
  11. 19. advantage – is the number of times a machine multiplies the effort force
  12. 20. Force – the combination of all of the forces acting on an object.
  13. 21. Machines – machines that work with one movement.
Down
  1. 1. force – is a force between any two objects.
  2. 2. - is found by dividing the change in the velocity of the object by the change in time
  3. 3. Force – the force applied to a simple machine
  4. 4. - the act or process of changing position or place.
  5. 7. - the tendency of an object to resist a change in motion
  6. 8. Force – the force exerted by the machine
  7. 9. - the unit used to measure force
  8. 11. 2nd Law – states that the acceleration, a, of an object is directly related to the net force, F, applied to the object and inversely related to the mass, m, of the object.
  9. 12. – the distance an object moves per unit of time
  10. 16. velocity – occurs when the force of air resistance becomes large enough to balances the force of gravity.
