Picture of Physics : Learn Physics the fastest way
Being a A+ student in Physics in my college didn't come from anywhere but my own strategy and hard work. During my basic physics classes i was bored and seemed a miss step in my career but then i found a easy way , a secret method actually to like, love and get the most in physics. So here i am to help you get started with physics and become a A+ student at it. Also for the secret, its somewhere in the texts beyond.

Physics :

It is what help us to understand our world better and to use this understanding for the benefits of people and environment. It involves the wide range of ideas and areas of investigations. It plays and important part in the the home, leisure, medicine and communication.
As with science it involves observations and experiments which are used to discover the relationship between things.

Who are the physicist ?
They try to make sense of relationships by developing theories and models. These theories are able to predict further behavior which can then be tested by experiments.

Physical quantities / Metric system

Note: Some people may think physics is really hard and confusing , that's right it is and that's what i still think, but remember its like a challenge and you need to refer this to real life situations and fight it to beat it. Just think it as a video game where you have evil bosses as formulas and equations and you are the ultimate formula killer etc.... have fun with something and you will learn. You know how i used to study ? . Well basically i wrote down a couple of problems in each A4 paper and then act as i am a super genius that is sent to earth to crack the most difficult equation. Then i used to make sounds say words and then solve and fall asleep. the next morning when it was exam time and the same kind of question appeared i was like " wow , it's time for super genius kid" hahah...sounds funny no ? ...but guess what i scored 20/20 in that exam , see what i mean ?...

System international Units - It is the standard system of units to measure all physical quantities , in other words the units in which the answer you write is gonna be in.

Length - Meter (m)
Mass - kilograms (kg)
Time - Seconds (s)
current - Ampere (a)
Temperature - kelvin (K)
Intensity - Candela (Cd)
Amount of substance - Mole (Mol)

Standard Prefix Multiplier

Tera - 10 * 12 ( * = power of)
Giga - 10 * 9
Mega - 10*6
Kilo - 10* 3
Centi - 10*-2
Milli - 10*-3
Micro- 10*-6
Nano - 10*-9
Pico - 10*-12
Peta - 10 *15
Femto - 10* -15

Exapmle 1 :

10 pM ----> M

10 x 10 * -12 m = This how you convert Pico Meter to Meter

you tell em JACK4U. yea upgrade that gram yo, you know all the little future dopeslingers, i meant dopple ganger, sorry no backspace, wait a minute where am i? you leave me and my kin alone ya hear i wouldve put a period but i hit backspace on accident. oh well.






Aww will there be more?

I'm loving it so far!

thanks ^_^

easy understanding

Good 'ible overall; one little nitpick after a brief read through - the standard for distance is meters, not kilometers; kilo is one of the prefixes you have listed. Also, here in America the standard units aren't metric. They are used by some, but not universally accepted - so you may wish to make mention of that. I guess that was two nitpicks rolled into one. 8o)
wow, I screwed up in picking nits, lol. You have meters/kilometers right, it was grams/kilograms you got wrong. the 'standard' is a gram, not a kilogram. kilo is (as you mentioned) a prefix.
PKM karossii6 years ago
Ditto Karel Jansens, the kilogram is the standard unit. There's probably some hilarious historical reason why that is, but unless you are using cgs (centimetres/grams/seconds), a non-SI metric system, the standard mass is the kilogram.
lemonie PKM6 years ago
I think the historical reason is a lump of metal somewhere in mainland Europe. Being an old thing, I guess that being able to achieve a higher accuracy measuring 1000g over 1g may have been part of it? L
A kilogram is 1000 cubic centimeters (cubic decimeter) of water. The centimeter is in turn 100th of a meter. A meter is one ten million of the distance to from the equator of earth...

In theory...

...but owing to measurement error and one of science's epic personality feuds, it's actually way off to point of being arbitrary. 

All measurement is really the linking of the degree or scale of one natural phenomena to another e.g. time is linked to the motion of astronomical bodies. 
PKM lemonie6 years ago
Well the SI mass has to fit in with the metre and second, both of which (AFAIK) have historical roots beyond the kilogram. The puzzling bit is why the base unit isn't called a gram, but I think the gram existed in its more-or-less present definition (1cm3 of water) before SI was around. It's actually an interesting bit of history.
I think you'll find that the standard of mass is indeed the kilogram, and not the gram. In fact, the actual standard is the physical reference kilogram they keep in France somewhere (Sèvres?).

Yeah Kilogram is it, at least what we use in Fiji and Britain.
arylic (author)  karossii6 years ago
Karosi, kilogram is the (SI) unit. Read below comment.
Standard scientific units are SI in the US, at least if you're publishing in a decent journal.

arylic (author)  lemonie6 years ago
Yeah thats what i mean, Standard international units (si)
arylic (author)  karossii6 years ago
oops look like a error, sorry for that ill get to it. Thanks for the advice anyways.

I'm not trying to be a priss or anything but I think he is trying to write it out so young teens nowadays can understand it. I am 13 and I never heard of physics yet, but I think I'm getting a hang of it because I understand him. The way you said how he should of said it confused me. So I think it's fine just the way it is. I had to make a stupid account just for that!

The concepts you are explaining are sdound and it looks like you understand the material, but to be honest your sentence structure and the general layout of this information is a mess. Try to write fewer run-on sentences- constrain a sentence to a conveying a single idea, and start a new paragraph when you change topic. (And yes, I know I'm terrible at overusing hyphens when I should break sentences; it's a terrible habit.)

For instance:
you would answer ohh...my weight is 71 kg , say that to a physics teacher or someone who knows it and they would laugh at you. Why ? because That means your 7.1 heavy or kg.
I am totally familiar with the concept of weight and mass and I can't follow this sentence. You also say "if your mass on earth is 710 N and on moon will mass the same 710 N." while explaining how Newtons measure weight (which changes with gravity) and kilograms measure mass, which doesn't.

You wrote
(Weight) is the gravitational pull on an object it is depended on the objects size and what it is made up of. Basically it means how much the power is used by the earths magnet to pull you. Units is Newtons (N).

Weight is the force exerted on an object due to gravity. Weight, like any other force, is measured in Newtons (N). An object's weight depends on the object's mass and the value of gravity (10 Newtons per kilogram on Earth)

The "earth's magnet" part could be a useful analogy, though I'm not sure about that either, but here it's just confusing the matter (no pun intended).

While I appreciate the idea behind this Instructable, I don't think it will really help anyone who doesn't already know the subject. It could be good if rewritten in a more clear style, but as it is will probably just confuse people.

Thanks for your great review Pkm , i am glad for your great response. Since this is my first try at a documentary and detailed guide i would be updating it with your advices. Thanks again.
It's My Beutiful Newtons. That makes me happy!

There is no way you can ever post ANYTHING physics related on the internet and not get nitpicked to hell for it, unless you have a degree in it. Even then, it's pretty hard.
arylic (author)  whatsisface6 years ago
What are you trying to say ?
Good question.
arylic (author)  whatsisface6 years ago
Oh, now i understand you mean that my instructable will get criticisms ? until i have a degree. I must say you are wrong. I don't need a degree , i have personal experience and knowledge to share my skills with you .

I am building a workbench. (And will put up an instructable when I'm done.) I'm using an Ikea oak countertop, and while carrying it into the house, I dropped it on my foot. Physics, I think, I have a pretty solid understanding of.
arylic (author)  jdege6 years ago
MM...yeah physics is everywhere from walking to talking to anything.
