Ruvanjani was told to switch on motor by her mother. Since the tank at the top of her building is empty, water is filled from the well. After the tank is full, she switched it off. She went near the tap opened it and washed her hands and legs with water from the tap for ten minutes. What concept is hidden in this scene.
What are the different energies at different position from the tank to the Tap.

Explanation

From this incident, when water rises from the well to the tank, Energy changes from kinetic to Potential Energy. When water is stored fully in the tank, the total energy is wholly Potential (P.E. = mgh) 'h' is the height from the ground level.
From the Tank to the tap, the energy changes from potential to kinetic energy. Here Kinetic Energy, `K.E.=(1)/(2)mv^(2)'v'` is the speed of water. At the tap, P.E = 0.
