Solar Planets
Planets in the universe is composed of eight major planets currently daitur by the world's space systems. It has also drawn protests some time ago when one of the planet is not appropriate as a planet because of their small size.

According to the IAU (International Astronomical Union) in accordance with the new definition, then there are eight planets in the Solar system:
1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune
High Current and Low Current
High currents and Low currents have a very clear distinction, is the sum of the currents used in a job they do. This term is actually growing in the industry.
boundary weak and strong current flow is quite clear but in some modules, PCB or electronic parts the other two terms can be joined for example, inverter, rectifier, or power supply, even in DC-DC converter.
In the industrial world, people who take care of electrical power such as the National Electricity Company line air conditioners, generators, power networks for the machines. they are divided into groups of strong currents.
while orang2 who are involved in the computer hardware, monitors, communication tools, the module controller, PLC, microcontroller, and the like used to enter the weak current.
In schools this is usually separate disciplines such as strong currents installation electric department, industrial electricity, etc., while the weak current department is electronics, industrial electronic, electronic communication, or even the instrumentation industry classifications into the weak current.
but in reality the industry and keeping this term is absent and only have one term that is part electric.
This explanation is only a general description, and I think quite hard to distinguish the term is based on the value above the current instance 1Ampere called strong flows because orang2 who worked with the inverter device can be achieved when they are grouped 15A weak currents, even at times a strong current of people just install the tool which the current consumption of only 0.2A.
so anything with the voltage magnitude is quite difficult to distinguish for this term.

NEWTON'S LAW
Newton laws were first launching by Sir Isaac Newton in his work Philosophiae Naturalis Principia Mathematica, first published on July 5, 1687. Newton used them to explain and investigate the motion of many physical objects and systems. Newton's laws are applied to bodies (objects) which are considered or idealized as a particle, in the sense that the extent of the body is neglected in the evaluation of its motion, i.e., the object is small compared to the distances involved in the analysis, or the deformation and rotation of the body is of no importance in the analysis.
Newton's First Law of Motion:
Newton's Second Law of Motion:
Newton's Third Law of Motion:

Newton's First Law of Motion:
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Newton's Second Law of Motion:
II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
Newton's Third Law of Motion:
III. For every action there is an equal and opposite reaction.
Alphabet In Physics
Alphabet In physics create various quantities and units to describe natural events (also artificial) that occur. To write it, were created symbols relating to mention, who came from several sources. Some quantities and units named after its discoverer, while others are named in English. Other even more magic again. All of these symbols would need to be shortened writing, often becomes one letter only.
Sample letter used by the physicists:

Sample letter used by the physicists:
A: Ampere, unit of electric current; a for acceleration or acceleration.
B: magnetic induction field. Probably derived from Biot-Savart.
C: Coulomb, unit of electric charge, c for the speed of light.
D: The electric field shift (displacement), d is often used for distance (distance)
E: Energy; electric field (electric field). e for the electric charge of electrons.
F: Force (force); f for frequency.
G: Newton's gravitational constant, g is used for the acceleration of gravity.
H: magnetic field due to electric current. Also H for Henry, the unit of inductance. h for Planck's constant.
I: Electric current.
A: The Joule, a unit of energy. Also for the electric current density.
K: Usually used as constants (eg: F = k q1 q2 / r2). k for Boltzmann's constant.
L: Liter; angular momentum, orbital quantum number. Also commonly used for long (length).
M: mass, magnetization, meters.
N: Newton, the unit of force. Also the main quantum number and the number of particles (number) in a mole.
O: Well, this letter is not used because it looks like the number zero. If only the other form, may be used as the unit of resistance, Ohm.
P: Power (power); pressure (pressure), electric polarization, p for the electric dipole moment and linear momentum.
Q: Often used in thermodynamics for business. q for electric charge.
R: usually used for the radius of the circle (radius) and distance (range).
S: Entropy. s for second (second) and spin in quantum physics.
T: Time; period; temperature. Also T for Tesla, a unit for magnetic induction field.
U: Internal energy. Sometimes used to indicate the speed, if the letter v is used.
V: The speed, the velocity. Also quantities and units of voltage (voltage and volts) and the potential in general.
W: Business (Work). Watt is a unit of power.
X, Y, Z are used as coordinates. Y for Young's modulus; in nuclear physics, Z represents the number of protons in the nucleus.
