Solution

  • A sheet of paper will fall slower than one crushed into a ball. This is because the air provides frictional resistance to the velocity of falling items.
  • The resistance offered by air to the sheet of paper is greater than the resistance offered by air to the paper ball because the sheet has a bigger area.
