  1. 2. -the tendency of an object to resist a change in its motion
  2. 4. -a friction force that opposes the motion of an object through a fluid
  3. 6. -a friction force that opposes the motion of an object as it slides over a surface
  4. 8. -the amount of matter in an object; a measure of the inertia of an object, which depends on the amount of matter the object contains
