Absolute location is a place's exact spot on a map, while relative location is an estimate of where a place is in relation to other landmarks. Absolute location is defined by latitude and longitude measurements. Relative location is used in conversational language and for giving rough directions.Know More
Absolute and relative location are two common methods of relating where streets, cities, stores and other important places are found on Earth. These systems of measurement are sympathetic to one another, with relative locations defined by their distribution around absolute locations on a map.
Absolute locations are used for scientific measurements. They are essential for cartography, meteorology and sciences that rely on the placement of physical landmarks on the Earth's surface to make accurate predictions or generate clear conclusions. Even astrology and space exploration need absolute location and technology tied to them to make flights and exploration successful.
Relative locations are more colloquial and defined by their relation to other places. These are not scientific or absolute measurements, but they do offer familiarity and ease of understanding. That makes them especially important for giving directions or remembering routes. Relative locations make it easy to associate places with one another in a way that generates a personal map of a landscape.Learn more about Motion & Mechanics
A truss consists of a set of members that act in compression or tension as a unit, and truss bridges stay up because of the forces that pull outward on the ends of the tension member, forming a triangular structure that keeps the bridge in place. A triangle is the ideal shape to hold this tension because a triangle does not experience distortion from the pushing and pulling of stress.Full Answer >
Because rectilinear motion takes place in one straight line, examples include a train following a straight set of tracks, a baseball thrown in a gravity-free vacuum or a penny that someone drops from the top of a tall building, heading straight to the ground. Rectilinear motion is the opposite of curvilinear motion, which involves movement along a fixed curve.Full Answer >
Relative location is a location stated in terms of its distance and direction from another location. It contrasts with absolute location, or location based on a general coordinate system. Relative location is by far the most common way of locating places and things in casual use.Full Answer >
The difference between hydraulics and pneumatics is the medium used in each system to perform work. Hydraulics employ fluids, such as oils, while pneumatics utilize compressed gases, such as carbon dioxide or atmospheric air.Full Answer >
