Answer: Global Positioning System (GPS)
Explanation:
Geographic Information Systems consists of a system of satellites that orbit the earth on precisely paths, broadcasting highly accurate time and location information is known as Global Positioning System (GPS). The Global Positioning System consists of various satellites that orbit the Earth and make it possible for people with ground receivers to pinpoint their geographic location. The signals also allow the electronic receiver to calculate the current local time to high precision, which allows time synchronisation.
When the object slides across the rough surface some of its potential energy will be lost to friction.
<h3>Conservation of mechanical energy</h3>
The law of conservation of mechanical energy states that the total mechanical energy of an isolated system is always constant.
M.A = P.E + K.E
When the object slides across the rough surface, some of the potential energy of the object will be converted into kinetic energy while the remaining potential energy will be converted into thermal energy due to frictional force of the rough surface.
P.E = K.E + thermal energy
