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.

The difference in the throws can be attributed to the combination of mass and speed, which both play a role in determining the kinetic energy. The 16-pound shot has a greater mass than the 12-pound shot, which means it requires more force to accelerate it to a certain speed. Additionally, the athlete may have applied more force and generated more speed when throwing the 12-pound shot, resulting in a greater kinetic energy and a longer throw.
