An athlete is practicing shotput using a 16-pound shot, and he throws it 40 feet. He then uses a 12-pound shot and throws it 50 feet. In three to four sentences, explain why there is a difference in these throws using the ideas of mass and speed and how each relates to kinetic energy.(4 points)
The difference in the throws can be explained by the concepts of mass and speed, which are related to kinetic energy. The athlete was able to throw the 16-pound shot a shorter distance because it had more mass, which required more energy to move. The 12-pound shot, on the other hand, had less mass and was easier to move, allowing the athlete to throw it a greater distance. The speed at which the shots were thrown also played a role in the difference in distance, as the faster the shot is thrown, the greater its kinetic energy.
The difference in the throws can be attributed to the concepts of mass and speed, which directly impact the kinetic energy of the shots. Kinetic energy is directly proportional to both mass and the square of velocity. The heavier 16-pound shot has more mass, resulting in a greater amount of potential energy that can be converted into kinetic energy during the throw. Moreover, the athlete must have applied more force or generated a higher velocity to throw the 12-pound shot farther, indicating an increase in kinetic energy due to a combination of increased mass and speed.
The difference in the throws can be attributed to the concepts of mass and speed, which are related to the kinetic energy of an object. In the first throw, the athlete used a heavier 16-pound shot, resulting in a higher mass. Since kinetic energy is directly proportional to mass, the shot with higher mass would have more kinetic energy, helping it travel a shorter distance. In the second throw, the athlete used a lighter 12-pound shot, but it was thrown faster. As kinetic energy is also directly proportional to the square of speed, the shot with higher speed had more kinetic energy, allowing it to travel a greater distance.
