The document discusses the direction of acceleration due to gravity for various objects in motion. It asks students to draw arrows indicating the direction of acceleration at different points in the paths of objects like a pebble dropped from a bridge, a baseball tossed into the air, and a football thrown at an angle. In all cases, the acceleration due to gravity points downward toward the center of the Earth. While the masses of objects may vary, their acceleration has the same downward direction and approximately 9.8 m/s2 magnitude on Earth.
