An Introduction to Force
In this section of the textbook, we will begin our discussion of the new (to us) concept called force. But before you get started, why don't you challenge yourself with the lunar lander game at the right? Before you hit the Start button in the lunar lander game, make sure you look at and understand the game controls shown in the lime green box. Your goal is to land the lunar lander as gently as possible on the surface of the moon. In other words, you need to use the thrust of the lander to attempt to counteract the gravity of the moon. Both thrust and gravity are forces, by the way. Good luck!
