• 19 centuries later, who proposed that all objects experience same downward acceleration when neglecting the effect of air resistance?


  Galileo
• Air resistance is sometimes referred as?

  air friction
• What is free fall motion?

  any motion of an object or body solely influenced by gravity
• What is the acceleration of gravity?

  -9.8 m/s^2
