Today, as I was helping my boyfriend clean out his garage, he found a basketball lying around and began tossing it up in the air and dribbling it. Then I remembered that this could be applied to what we were learning right now in physics. He threw the ball up at a certain velocity, and then when it stopped and started heading toward the ground, the velocity changed. At the point where the ball stopped and turned to head toward the ground, the velocity was zero. Also, the ball was accelerating at a rate of -9.8 meters per second squared, due to gravity. When the ball made contact with his hand again, the velocity was once again zero, and the direction changed.
