Use the picture of the girl swinging. How would you describe her energy at position Z?
1She has high potential energy and low kinetic energy.
2Her kinetic and potential energy are equal and very low.
3Her kinetic and potential energy are equal and very high.
4She has high kinetic energy and low potential energy.
Based on the picture of the girl swinging, at position Z, the answer would be:
1. She has high potential energy and low kinetic energy.
At position Z, the girl has reached the highest point of the swing, so she has high potential energy since she is at her maximum height from the ground. However, she has low kinetic energy because she has momentarily stopped moving and is about to begin moving back down, so her velocity is momentarily zero.

Based on the picture of the girl swinging, at position Z, the answer would be:
1. She has high potential energy and low kinetic energy.

However, she has low kinetic energy because she has momentarily stopped moving and is about to begin moving back down, so her velocity is momentarily zero.
To describe the girl's energy at position Z, we need to understand the concepts of potential energy and kinetic energy.
Potential energy refers to the energy an object possesses due to its position or condition. In this case, the girl's potential energy would be highest when she is at the highest point of her swing, where her height from the ground is the greatest.
Kinetic energy, on the other hand, refers to the energy an object possesses due to its motion. As the girl swings back and forth, her speed and motion can determine her kinetic energy at any given point.
To determine the answer, we should examine the picture and analyze her position. If position Z represents the highest point of her swing, then we know she has reached maximum potential energy. At this point, her motion is momentarily paused before changing direction. Since she is not moving, her kinetic energy would be at its lowest point.
Based on this information, the correct answer would be:
1. She has high potential energy and low kinetic energy.
By understanding the concepts and analyzing the given scenario, we can accurately describe the girl's energy at position Z.
