Question

Devon is playing with a yo-yo. A yo-yo has an axle in the middle of two plastic halves. A string is tied around this axle. As Devon moves his hand, the yo-yo goes up and down. The yo-yo converts potential energy to kinetic energy as it moves. Which of the following pictures represents the yo-yo with the most potential energy? A. X B. Y C. Z D. W

Answer 1

Answer:

second image or  B. Y

Explanation:

Potential energy is defined as the stored energy of an object when work is done against a force.

The second image in which yo-yo is ready to stretch out, represents the yo-yo with the most potential energy because the distance is highest from the ground and so yo-yo at this position will have highest gravitaional potential energy. The potential energy will be converted into kinetic energy when released in air.

Hence, the correct image is  "second image" or "B. Y"
