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.(4 points)
The 16-pound shot has more mass than the 12-pound shot, which means it has more potential for kinetic energy. Additionally, when the athlete throws the 16-pound shot, he might exert more force and create a higher velocity compared to when he throws the 12-pound shot. This increase in mass and velocity results in a greater kinetic energy, allowing the shot to travel a shorter distance.
The difference in the throws can be explained by the concepts of mass and speed and how they relate to kinetic energy. The 16-pound shot has a greater mass compared to the 12-pound shot, which means it requires more force to move and accelerate it. The athlete may not be able to throw the 16-pound shot with the same speed as the 12-pound shot, resulting in a shorter distance. Additionally, kinetic energy is directly proportional to both mass and the square of speed, so the combination of lower mass and higher speed with the 12-pound shot results in greater kinetic energy, enabling it to be thrown a longer distance.
The difference in the throws can be attributed to both mass and speed, which affect the kinetic energy of the shot. Kinetic energy is directly proportional to both mass and the square of velocity. In the first throw, the athlete used a 16-pound shot and threw it 40 feet, resulting in a certain amount of kinetic energy. In the second throw, the athlete used a 12-pound shot, but because he was able to throw it 50 feet, the shot had a higher velocity, resulting in more kinetic energy.
