Stretched Slinky:
When a slinky is stretched, it possesses elastic potential energy. This is a type of potential energy that arises from the deformation or stretching of an object. The energy is stored in the slinky as the coils are pulled apart from their equilibrium position. The more the slinky is stretched, the greater the amount of potential energy it possesses. This potential energy can be released when the slinky is allowed to return to its original shape.

Flowing Water:
Flowing water possesses kinetic energy. Kinetic energy is the energy of motion. When water flows, it moves with a certain velocity and mass, which gives it kinetic energy. The amount of kinetic energy depends on the mass of the water and its velocity. The faster the water flows or the greater its mass, the more kinetic energy it possesses. This energy can be harnessed and converted into other forms, such as mechanical energy in water turbines or electrical energy in hydroelectric power plants.

Stretched Rubber Band:
A stretched rubber band possesses elastic potential energy, similar to a stretched slinky. When a rubber band is stretched, it stores potential energy in its molecular structure. The energy is stored as the rubber band is pulled apart from its original length. The more the rubber band is stretched, the more potential energy it has. This potential energy can be released when the rubber band is allowed to return to its original shape, such as when it is released or when an object is launched using the stored energy.

Overall, the energy possessed by a stretched slinky, flowing water, and a stretched rubber band can be categorized as elastic potential energy in the case of the slinky and rubber band, and kinetic energy in the case of flowing water. These different types of energy play important roles in various phenomena and can be converted into other forms of energy for various applications.
