4. Question 1 When an airplane flies directly into the wind, is the speed of the airplane across the ground more, less, or unaffected? Answer: Less speed. In fact, if the airplane's speed matches wind speed, the airplane would stay in one place (like a bird often does when it faces the wind).

5. Question 2 When an airplane flies directly with the wind, so the wind comes from behind, is the speed of the airplane across the ground more, less, or unaffected? Answer: It is more.

6. Question 3 When an airplane flies in a cross wind, so its nose is pointing at right angles to the wind, is the speed of the airplane across the ground more, less, or unaffected? Answer: It is more! How much more and in what direction is found by vectors!

7. Projectile Motion Free Fall => distance = Speed ∙ time

9. V y = g ∙ t  t = 2 ∙ V y / g  R = V x ∙ t
