Question

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)

Answer 1

make it shorter

Answer 2

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.
