Chapter 5: Work and Energy
... Work is done only when the force is parallel to the displacement. If the force is perpendicular to the displacement of an object, work is not done on the object. When the force on an object and the object’s displacement are in different directions, only the component of the force that is parallel to ...

Alternative energy
Alternative energy is any energy source that is an alternative to fossil fuel. These alternatives are intended to address concerns about such fossil fuels.The nature of what constitutes an alternative energy source has changed considerably over time, as have controversies regarding energy use. Today, because of the variety of energy choices and differing goals of their advocates, defining some energy types as ""alternative"" is highly controversial.In a general sense, alternative energy as it is currently conceived, is that which is produced or recovered without the undesirable consequences inherent in fossil fuel use, particularly high carbon dioxide emissions (greenhouse gas), an important factor in global warming.
