The document discusses free fall and projectile motion. It explains that free falling objects are only acted upon by gravity and accelerate downward at 9.81 m/s2. Projectiles are also only affected by gravity and may be dropped, thrown upward vertically, or thrown at an angle. The motion of projectiles has independent horizontal and vertical components, with horizontal velocity remaining constant and vertical motion experiencing gravitational acceleration.

1. Free-Fall & Projectiles

3. A tennis coach, a ball machine, and a tennis racquet are dropped from the umpire chair. As free-falling objects, they will both hit the ground at the same time.

12. THE END!
