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 shotput throws can be explained by the principles of mass and speed in relation to kinetic energy. Kinetic energy is directly proportional to the mass and the square of the velocity of an object. In the first throw with the 16-pound shot, although the mass is greater, the distance achieved is shorter due to a lower velocity. In the second throw with the 12-pound shot, although the mass is smaller, the distance achieved is longer due to a higher velocity.
The difference in the throws can be attributed to both mass and speed, which affect the Kinetic energy. Kinetic energy is directly proportional to the mass of the object, so the 16-pound shot would have more kinetic energy compared to the 12-pound shot, assuming that both shots were thrown at the same speed. Additionally, the speed of the shot also affects its kinetic energy, as it is proportional to the square of the velocity. Therefore, if the athlete threw the 16-pound shot at a higher speed compared to the 12-pound shot, it would result in even greater kinetic energy and potentially a longer throw.
The difference in the throws can be explained by considering the concepts of mass and speed and their relation to kinetic energy. Kinetic energy is directly proportional to both mass and the square of speed, so a larger mass and higher speed will result in greater kinetic energy.
In the case of the shotputs, the 16-pound shot has a greater mass than the 12-pound shot, leading to higher kinetic energy when thrown. This higher mass allows for more force to be exerted on the shotput during the throw. Additionally, the athlete might have generated a higher speed during the throw of the 16-pound shot compared to the 12-pound shot, which further increases the kinetic energy.
