If Zephyr is standing on a cliff's edge and Juniper is standing on the ground below, but a significant distance away from the cliff such that she cannot see Zephyr directly, what happens when Zephyr drops a ball off the edge of the cliff? Respond briefly.
When Zephyr drops the ball off the edge of the cliff, gravity acts on the ball, pulling it downwards. As the ball falls, if there are no other obstructions, it will continue to accelerate towards the ground due to gravity. From Juniper's position on the ground and at a distance away from the base of the cliff, she will not be able to see the ball immediately after it is dropped. Only when the ball falls below the height of the cliff and enters her line of sight will she be able to see it descending. The exact moment when Juniper sees the ball depends on her distance from the cliff and the height of the cliff. If Juniper were closer to the cliff or the cliff were not as tall, she might see the dropped ball sooner. If Juniper were directly underneath the point from which Zephyr dropped the ball, she still would not see the ball until it fell below the top of the cliff, at which point it could be very close to her, depending on her distance from the cliff's base.
