  1. 1. is the rate of change in a momentum.
  2. 6. is an object that is initially thrown into the air and continues to move on its trajectory acted upon by gravity
  3. 8. quickness of motion
  4. 9. a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
  5. 10. tending towards to the center of rotation by centripetal force.
  6. 11. in a direction of an tagent
  7. 13. act or power to resist.
  8. 16. applied to an object produces a equivalent vector change in its linear momentum.
  9. 18. is a collision in which the total kinetic energy after colliding is less than before the collision.
  10. 20. an instance of one moving object or person striking violently against another.

  1. 2. is defined as one in which there is no loss of kinetic energy in the collision.
  2. 3. weight
  3. 4. is a measure of the difficulty encountered in bringing moving objects to rest.
  4. 5. a motion when the objects turns about an external axis.
  5. 7. Is the rate of change of velocity of an object with respect to time.
  6. 12. is a branch of classical mechanics which describes the motion of points (alternatively “particles”).
  7. 14. a motion when an object turn s about an internal axis or the axis between the object.
  8. 15. MOTION kinematics and newton's second law of motion
  9. 17. a change in position of an object over time.
  10. 19. a space or interval
