You are now done for this chapter! Only the weekly questions, and maybe the DIY are left and you’ll be at the end of the third week! After finishing this week’s lectures and exercises, you should be able to understand the concept of a force balance, and be able to determine the terminal velocity of various moving objects (hailstone, air bubble, and maybe other examples that you can think about yourself). Next week, the course will continue by providing deeper insights into heat and mass transfer.
