Document Summary
Motion: understand how humans can tap into the force of gravity to get useful energy. Understand where useful energy is lost in the process: recognize the factors that affect the trade-off between the human and environmental impacts of a dam and the desire to maximize the energy output, motion. Motion is converting movement into usable forms of energy. Examples of these could be tidal power or hydroelectric dams. The kinetic energy that water has as it falls can be converted to other forms of energy such as electric energy. When looking at the height of a dam, you want to look at how high the reservoir of water is, which is called the head height. You always want to build a dam higher than the reservoir of water, because it calculates for if the reservoir were to grow. If the dam was not high enough then it could lead to overflow and flooding.
