The difference in the throws can be attributed to both the mass and speed of the shots. The 16-pound shot has more mass compared to the 12-pound shot, which means that it contains more kinetic energy when thrown. Additionally, the athlete may have exerted more force and achieved a higher speed when throwing the 16-pound shot compared to the 12-pound shot. The combination of higher mass and greater speed resulted in a longer throw for the 16-pound shot.make this like a 8th grader wrote it

The reason why the shots went different distances is because of how heavy they were and how fast they were thrown. The 16-pound shot was heavier than the 12-pound shot, so it had more energy when it was thrown. The person throwing the shots may have also pushed harder and made the 16-pound shot go faster than the 12-pound shot. Because of the combination of being heavier and going faster, the 16-pound shot went further than the 12-pound shot.
