The difference in the throws can be explained using mass and speed. The 16-pound shot is heavier, which means it has more mass, but the athlete might not be able to throw it as fast as the lighter 12-pound shot. Kinetic energy depends on both mass and speed, so even though the 16-pound shot has more mass, the faster throw of the 12-pound shot gives it more energy, allowing it to go further.
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. explain why there is a difference in these throws using the ideas of mass and speed and how each relates to kinetic energy.
