Honestly.. I am only .. But I want to learn this stuff at a young age..
What do all these mean?
Any possible way to learn without school, this summer?

Probably not.Originally Posted by Brian
If you really want to learn physics you need to first get basic mathematics under your belt.
That means that before you tackle physics you need to be reasonably proficient in at least basic algebra and trigonometry.
And frankly, a decent understanding of physics requires elementary calculus.
If you are 14 you have plenty of time to learn these subjects. Maintain your apparent high level of interest and things will work out fine.
Besides, summer is almost over. Have fun and apply yourself in the fall.
is the equation to describe the conversion rate between mass and energy.Originally Posted by Brian
E is energy in J
m is mass in kg
c is the speed of light (approx. 3x10^8)
so, if I had 1kg of matter, if I could turn it all into pure energy, I would get
DrRocket, while he may not come to fully understand everything he may hear at 14, that is no reason to try to stop him from learning.
Good one turtle. Ageists shouldn't speak of education.
The problem is that that explanation doesn't tell you anything about the equation, only what it's used for. To understand the why and the how of it would take an understanding in at least elementary physics and math up to trig. It's much more complex than a simple plugandchug equation, there is deeper meaning and connections with it that can't really be expressed in the simple explanation of the equivalence.
Read my article on the 'Credibility' of this Formula.Originally Posted by Brian
Granted, I am not a follower of much of the science that is being promoted by the 'power' faction today.
I am a disciple of the Galileo, Kepler, Newton, Planck and Bohr teachings that resulted from the Copernicun Heliocentric theory.

All that you proved in your article on "credibilty" is that you have none.
Galileo, Kepler, Newton, Planck and Bohr would be horrified to hear their names associated with your nonsense.
Agreed, Cosmo's "article" should be ignored until you understand everything about the derivation of Einstein's equation. For that you should know Calculus, and then read Einstein's papers on SR/GR.
After you understand that fully, you can appreciate Cosmo's comedy.
Even without that, you can appreciate how inane half of what he says is. Simple knowledge of a vacuum tells enough to know exactly how silly Cosmo is.
Half ???Originally Posted by Arcane_Mathematician
Maybe both halves. It doesn't seem fair to discriminate between the two.
Well, some of his BS isn't explicitly obvious BS if you don't have a good understanding of the science behind it, that's all I meant.
Hi,
I'm 16 and have been heavy into physics since I was 14.
You don't really need the maths if you're just pursuing an interest; you're not trying to solve problems or push the boundaries of human knowledge right?
I just borrowed a Year 11 (the second last year of school, 11th Grade or whatever) Physics text and read that. Also, go down to your local library and look for some books on physics. "A brief history of time" is really complicated and wordy but needs thought not maths. A really good book about E=mc^2 is "E=mc^2: A biography" it's very historical and talks about how the equation is used but it also goes into what it means, it's quite entertaining.
There are alot of paperback nonfiction books that take an entertaining, anecdotal light to specific problems, look them up in the library.
One occasion where books > internet,
for that little bit. I kinda get that now.is the equation to describe the conversion rate between mass and energy.

Also childoflore.. I don't really think you could learn from just "READING" a book..
Also... If "E" is the energy in "J".. What does "J" mean?
So instead of 1kg, what would 2kg be?? I tried this.. But I get confused.
J is Joules, a measurement of energy.Originally Posted by Brian
It is the work done when 1N of force acts on 1kg of mass.

Twice as much. is always the same, and is then multiplied by mass.Originally Posted by Brian
so for 2kg, it's
Yes, a Joule is a unit of energy.Originally Posted by drowsy turtle
No, a Joule is NOT "the work done when 1n of force acts on 1 kg of mass.
Energy or work occurs when a force acts over a distance. A Joule is the action of 1 Newton of force over a distance of 1 meter.
If you recall F=ma, you find that 1 Newton acting on a mass of 1kg produces and acceleration of 1 meter per second per second.
