<span>The water reduces friction between the surface you are standing on, and your feet.</span>
This inaugural journey may be slow-going for those who already know their way around the solar system, as our place in it is explained by a “cosmic address” (Earth<span>, solar system, Milky Way, local group, Virgo supercluster, observable universe), but interest will be held by the sharp and mesmerizing graphics.</span>
While sliding down a hill in a sled, the force of gravity causes the sled to accelerate down the hill. The force of friction eventually causes the sled to stop. the friction force partly cancels some of the gravity force pulling the sled down. These two forces affect many motions on Earth.
Explanation:
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s)
which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running.
