What you'll learn

  1. Pull the bottom: Friction must drag the top block along
  2. Too hard a pull: Once it slips, each block has its own acceleration
  3. Pull the top: Now friction drags the bottom block
  4. Top pulled hard: Two blocks, two equations
  5. A rough floor: The floor pulls back too
