In a building a system is installed that uses the geothermal energy in summer to cool the building and the same energy to warm t
Inga [223]

A ground source heat pump takes advantage of the naturally occurring difference between the above-ground air temperature and the subsurface soil temperature to move heat in support of end uses such as space heating, space cooling (air conditioning), and even water heating. A ground source or geo exchange system consists of a heat pump connected to a series of buried pipes. One can install the pipes either in horizontal trenches just below the ground surface or in vertical boreholes that go several hundred feet below ground. The heat pump circulates a heat-conveying fluid, sometimes water, through the pipes to move heat from point to point.

this system works during the winter due to it being a sub-ground energy source.

How does the friction affect the total time a pendulum is in motion? And what could cause this friction in the real world?
pentagon [3]

Friction decreases the total time that a pendulum is in motion.

If we consider a pendulum in motion, in accordance with Newton's law, the pendulum will continue moving unless it is acted upon by an external force.

In the case of the pendulum, the external force that acts on it is the air resistance or friction. As a result of this friction, the pendulum will eventually come to a stop.

In the real world, the surface of objects cause friction which causes moving objects to stop.
