Question

the image shows a dam. which descriptions best fit the labels? x: kinetic energy y: potential energy x: potential energy y: kinetic energy x: mechanical energy y: electrical energy x: electrical energy y: mechanical energy

Explanation:

• Potential energy is the energy stored in an object due to its position. In a dam, the water behind the dam (label \(X\)) has potential energy because of its height.
• Kinetic energy is the energy of an object in motion. The water flowing out from the dam (label \(Y\)) is in motion, so it has kinetic energy.

Answer:

X: potential energy; Y: kinetic energy (the second option)
