Across
  1. 4. force- forces applied to an object in opposite directions that are not equal in size
  2. 8. an influence tending to change the motion of a body or produce motion or stress in a stationary body
  3. 9. in a straight line, unless that state is changed by an external force.
  4. 10. other
  5. 13. the condition of a system when neither its state of motion nor its
  6. 16. speed- the speed does not change at all for each second of the motion
  7. 17. A force that tends to stretch or elongate something.
  8. 18. momentum that characterizes motion never changes in an isolated collection of objects
  9. 19. motion with the same speed and in the same direction unless acted upon by an unbalanced force.
  10. 21. force- equal in size and opposite in direction
  11. 22. friction- a force that keeps an object at rest
  12. 24. - the steepness of a line
  13. 29. the rate at which velocity changes with time, in terms of both speed and direction
  14. 30. a geometric object which has both magnitude or length and direction
  15. 33. speed- is the total distance traveled by the object in a particular time interval
  16. 36. its location relative to a reference point
Down
  1. 1. a property of matter by which it continues in its existing state of rest or uniform
  2. 2. of conservation of momentum- general law of physics according to which the quantity
  3. 3. The SI derived unit used to measure force
  4. 5. third law- when two bodies interact, they apply forces to one another that are
  5. 6. magnitude and direction to the force imposed on it.
  6. 7. the rate at which the position changes
  7. 11. Second Law- the time rate of change of the momentum of a body is equal in
  8. 12. force- the sum of all the forces acting on an object
  9. 14. energy state tends to change with time
  10. 15. a force that squeezes something together
  11. 20. due to gravity- the acceleration gained by an object due to gravitational force.
  12. 23. a force that resists the motion of one object against another
  13. 24. friction- the friction between two bodies that are in sliding contact
  14. 25. is a unit of weight
  15. 26. speed- the speed of an object at a particular moment (instant) in time
  16. 27. the distance traveled per unit of time
  17. 28. The movement by which the two elements of any jointed part are drawn away from
  18. 31. in magnitude and opposite in direction.
  19. 32. an object that is falling under the sole influence of gravity.
  20. 34. first law- the law of inertia An object at rest stays at rest and an object in motion stays
  21. 35. the quantity of motion of a moving body, measured as a product of its mass and velocity
