That is already taken care of. If you consider only vessel X, then the change in PE would betoforfiltum said:
Potential energy is the energy that an object possesses due to its position or state. It is the energy that can be converted into other forms, such as kinetic energy, and is typically measured in joules (J).
The loss of potential energy is caused by a change in the position or state of an object. This could be due to external forces, such as gravity or friction, or internal factors, such as a change in the object's shape or composition.
The potential energy of an object can be calculated using the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height or vertical distance from the reference point.
Examples of potential energy being lost include a roller coaster reaching the bottom of a hill, a ball rolling down a hill, a stretched spring returning to its original shape, and a book falling off a shelf. In each of these cases, the object's position or state has changed, resulting in a decrease in potential energy.
Yes, potential energy can be converted into other forms of energy, such as kinetic energy, thermal energy, or electrical energy. This conversion often occurs when an object is in motion or when external forces act upon it.
