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.
The difference in these throws can be explained by the concepts of mass and speed and their relationship to kinetic energy. The athlete threw the 16-pound shotput with less speed, resulting in a shorter distance. The 12-pound shotput was thrown with more speed, leading to a greater distance. According to the kinetic energy equation (KE = 1/2 * mass * speed^2), both mass and speed contribute to the overall kinetic energy. Thus, the combination of a higher velocity and a lower mass in the 12-pound shotput resulted in a greater kinetic energy, leading to a longer throw.
The difference in the throws can be explained by the concepts of mass and speed in relation to kinetic energy. Kinetic energy is directly proportional to an object's mass and the square of its speed. In the first throw, the athlete uses a 16-pound shot, which has more mass compared to the 12-pound shot used in the second throw. This higher mass translates to higher kinetic energy. Additionally, the first throw covered a shorter distance, indicating a lower speed. Therefore, the combination of higher mass and lower speed in the first throw resulted in less kinetic energy, leading to a shorter distance.
