The girl in the picture is at the highest point in swinging and starts to come down. Which statement best describes the changes in energy as she begins to descend?
Kinetic and potential
• energy are decreasing.
Kinetic and potential
• energy are increasing.
Potential energy is increasing, and kinetic energy is decreasing.
Kinetic energy is increasing, and potential energy is decreasing.
Kinetic energy is increasing, and potential energy is decreasing.
The correct statement is: Kinetic energy is increasing, and potential energy is decreasing.
To determine the changes in energy as the girl in the picture begins to descend, we need to understand the concepts of kinetic energy and potential energy.
Kinetic energy is the energy an object possesses due to its motion, and potential energy is the energy an object possesses due to its position or height above the ground.
In this scenario, as the girl starts to come down from the highest point in swinging, her potential energy is decreasing because she is descending from a higher position. At the same time, her kinetic energy is increasing because she is gaining speed as she moves downwards.
Therefore, the statement that best describes the changes in energy as she begins to descend is:
"Potential energy is decreasing, and kinetic energy is increasing."
