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

The yo-yo with the most potential energy is B.Y .Therefore , B.Y is correct .

Potential energy is a concept in physics that refers to the stored energy an object possesses due to its position, state, or condition.

When work is done against a force, potential energy is accumulated, ready to be converted into other forms.

In the context of gravitational potential energy, an object's height above a reference point determines the stored energy.

The higher an object is, the greater its potential energy.

Consider a yo-yo in the second image, suspended in the air and about to unravel.

At this point, it has the most potential energy because it is farthest from the ground.

As the yo-yo descends, the gravitational potential energy is transformed into kinetic energy – the energy of motion.

This transition occurs as the yo-yo moves closer to the ground, converting the stored potential energy into the energy of movement.

The interplay between potential and kinetic energy illustrates the fundamental principles of energy conservation, showcasing how energy can change forms but is ultimately conserved in a closed system.

The yo-yo's descent, from potential to kinetic energy, exemplifies this elegant relationship between different forms of energy in the physical world .

Answer:

second image or B. Y

Step-by-step 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"
