SCIENTIFIC laws..HELP?

Question

what are two laws of science that govern our lives like the law of gravity? and how our lives are changed by those two laws?

ive got thermodynamics and electromagnitism.........but i dont really get how to explain it.....

DO YOU GUYS HAVE ANY MORE SIMPLER LAWS...AND EXPLAIN?

THX ;]

Answer 1

electromagnetism, gravity, weak and strong nuclear forces.  

Answer 2

You can use Newton's Laws of motion. Look at this website:

It gives good explanations and examples.

Answer 3

there's electricity related phenomena:

Electrons and protons attract to each other, whereas same charged particles repel.  This interaction between the particles helps determine the structure of the universe.  Also, the discovery of electricity has helped people develop technology and improve their lives.

another one is a version of the 2nd law of thermodynamics:

Heat flows from hot to cold.  This property gives order to the processes that govern transfer of heat.  For example, if this law did not hold, then maybe you would have random transfer of heat between objects.  This would drastically change the structure of the universe.

Answer 4

Isaac Newton's law of universal gravitation is a physical law describing the gravitational attraction between bodies with mass. It is a part of classical mechanics and was first formulated in Newton's work Philosophiae Naturalis Principia Mathematica, first published on July 5, 1687. In modern language it states the following:

Every point mass attracts every other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between the point masses:

F= G m1m2/r2

Explanation:

Every point mass attracts every other point mass by a force pointing along the line intersecting both points.

So that means if the Earth rotation is to left, the moon's orbit to Earth is to left also.
