12 the girl in the picture is at the highest point in swinging and starts to come down which statement best describes the change in energy as she begins to descend
The statement that best describes the change in energy as the girl begins to descend from the highest point in swinging is:
Her potential energy decreases as her kinetic energy increases.
As the girl in the picture starts to come down from the highest point while swinging, there are changes in energy occurring. Here is a step-by-step explanation of the change in energy:
1. At the highest point, the girl possesses potential energy due to her position above the ground. This potential energy is at its maximum.
2. As she starts to descend, her potential energy decreases while her kinetic energy increases. Potential energy is converted into kinetic energy as she gains speed.
3. The decrease in potential energy is accompanied by an increase in kinetic energy. This means that the energy is being transferred from potential energy to kinetic energy.
4. As she continues her descent, her potential energy decreases further while her kinetic energy continues to increase. The kinetic energy reaches its maximum when she reaches the lowest point of the swing.
In summary, as the girl in the picture starts to come down from the highest point while swinging, her potential energy decreases while her kinetic energy increases. The energy is being transferred from potential energy to kinetic energy.
To understand the change in energy as the girl in the picture begins to descend from the highest point while swinging, we can look at the principles of mechanical energy.
Mechanical energy is the sum of two forms of energy: potential energy and kinetic energy. Potential energy is the energy that an object possesses due to its position or state, while kinetic energy is the energy of motion. Let's analyze the situation based on these principles.
When the girl is at the highest point in the swing, she has maximum potential energy and minimum kinetic energy. As she starts to come down, her potential energy decreases because she is getting closer to the ground. This potential energy is converted into kinetic energy as she gains speed during her descent.
Therefore, the best statement to describe the change in energy as the girl begins to descend would be: "The girl's potential energy decreases, while her kinetic energy increases."
