Jax is standing on a cliff edge and throws a stick horizontally off the cliff. Zara, who is standing at the bottom of the cliff, observes the stick as it falls. In what direction does Zara see the stick moving during its fall, and why does it move in this way? Provide a very brief response.
Zara sees the stick moving downwards at an angle, not just horizontally or vertically. This occurs because the stick is influenced by two factors simultaneously: the horizontal velocity imparted by Jax's throw and the vertical acceleration due to gravity. As the stick is thrown horizontally, it initially has a horizontal motion. Gravity then acts on the stick, pulling it downward, and causing it to accelerate towards the ground as it moves horizontally. The resulting path of the stick is a curved trajectory.
