What is happening?

• 1 Applying gravity
  • Yellow ball is being pulled down by the weight of its own gravity
  • The same is happening with the blue ball
  • As there’s no other force being applied to the balls they hit the ground at the same time

• 2 Applying other forces (air resistance)
  • Air resistance now is being applied to the balls
  • Their weight now affects the time they hit the ground

• 3 Applying friction
  • With the friction force the balls eventually will stick to the ground, as in the real world
