“Energy is not lost or destroyed, it is merely transferred from one party to the next.” – Sir Isaac Newton
In a discussion of energy the basic understanding revolves around the fact that there are three laws. These are simple laws dealing with energy and can be defined as follows:
Energy can neither be created nor destroyed. This means that you can’t make energy out of nothing— the total amount of energy in the universe is a constant. (Please note that this applies to a closed system – the Earth is not a closed system, the Earth receives energy all the time from the Sun).
Work is done upon an object whenever a force acts upon it to cause it to be displaced. Work involves a force acting upon an object to cause a displacement. In all instances in which work is done, there is an object that supplies the force in order to do the work.
An object that possesses some form of energy supplies the force to do the work. In the process of doing work, the object that is doing the work exchanges energy with the object upon which the work is done. When the work is done upon the object, that object gains energy. The energy acquired by the objects upon which work is done is known as mechanical energy.
The United States soccer team put on a clinic Sunday night, as it routed Japan 5-2 to win the 2015 FIFA Women’s World Cup.
Team USA scored two goals within three minutes, and was ahead 4-1 at halftime. While Japan did ultimately score two goals on the previously unstoppable American defense, it was never even close to being enough to compete with the U.S. team.
Carli Lloyd had a hat trick in the game, scoring three goals–one of them an impressive shot from the half-field mark.
The game ended up being the highest-scoring final game in the FIFA Women’s World Cup, and avenged America’s loss to Japan in the 2011 World Cup.
“Everybody, my friend, everybody lives for something better to come. That’s why we want to be considerate of every man – Who knows what’s in him, why he was born and what he can do? ”
