Question

1. application question: in lancaster county, pennsylvania, it is common for members of the amish community to use wind mills to pump water from underground to fill a tank for drinking water. the wind causes the turbine blades to spin, rotating a shaft, which is transferred through some gears to operate a pump, which pumps water up from deep below the ground to fill an above ground tank. identify the energy conversions happening at each step below.

a. wind blows (____________________ energy)
b. causing the turbine to turn, rotating shaft works pump(____________________ energy)
c. motion of water moving up from well (____________________ energy)
d. water in tank which is positioned 5 feet above the ground level ( ____________________ potential energy)

Explanation:

Step1: Identify wind energy type

Wind is moving air, so it has kinetic energy.

Step2: Analyze turbine - shaft - pump energy

The rotation of the turbine, shaft and pump involves motion, which is kinetic energy.

Step3: Determine water - motion energy

The moving water from the well has kinetic energy due to its motion.

Step4: Determine water - position energy

The water in the tank above the ground has gravitational potential energy because of its position relative to the ground.

Answer:

A. Kinetic
B. Kinetic
C. Kinetic
D. Gravitational
