Answer

Brief Explanations:

For the first question, the force of friction is directly proportional to the normal force, and as mass increases, the normal force (on a flat - surface) increases, thus friction increases. For the second question, sandpaper has a rough surface which creates more resistance and hence greater friction compared to ice, smooth wood, and glass.

Answer:

  • friction increases
  • sandpaper
