  1. 3. normally occur due to an explosion or the striking of one body against another.
  2. 4. is defined as the amount of work or the capacity of the machine to performed per unit time.
  3. 5. establish the x, y, z inertial frame of reference and draw the particle’s in order to account for all the forces that produce impulses on the particle.
  4. 6. in reality all particles must have___to posses mass.
  5. 7. a vector quantity which measures the effect of a force during the time the force acts.
  6. 8. is the ratio of the output of useful power produced by the machine to the input power supplied to the machine.
  7. 11. occurs when the direction of motion of the mass centers of the two colliding particles is along a line passing through the mass centers of the particles.
  8. 12. represent the principle of linear impulse and momentum of particle in the x, y, z directions, respectively.
  9. 14. one of the principle of linear impulse and momentum is used to solve problems.
  10. 16. the total linear momentum of the system of particles equivalent to linear momentum of ___.

  1. 1. the basic unit of power in FPS.
  2. 2. when the motion of one or both of the particles is at an angle with the line of impact.
  3. 3. the principle of linear and momentum for a system of particles moving relative to an ___.
  4. 9. if the time period over which the motion studied is very short, some of the external impulses may also be neglected or considered approximately zero.
  5. 10. is an outlined shape of the particle showing all the impulses that act on the particle when it is located at the same intermediate point along its path.
  6. 13. occurs when two bodies collide with each other during a very short interval of time, causing relatively large forces to be exerted the bodies.
  7. 15. is along a line passing through the mass centers of the particles.
  8. 17. one of the principle of linear impulse and momentum is used to solve problems.
  9. 18. one of the principle of linear impulse and momentum is used to solve problems.
  10. 19. if the solution yields a negative magnitude, the velocity acts in the___sense.
