In a room with an open window, Aarav and Jing stand with their backs to the window. A breeze starts blowing in from the window. Which direction will Aarav's or Jing's hair move and why? Provide a very brief response.
Aarav's and Jing's hair will move forward, away from the window. The wind is coming in from the window, which is behind them, so the momentum of the air particles will push their hair in the direction the wind is moving, which is towards the front of the room where Aarav and Jing are facing. This movement occurs because the wind applies a force on their hair, and objects in the path of the wind will generally move in the same direction as the flowing air if they are light and flexible enough, like hair.
