### Flash Labs NO.2 : Newton’s Law of Gravitation

22Aug08

It’s high time to support my physics by computers. Today I experimented with Newton’s Law of Gravitation for 3D and as far as it goes to one object it works great. However I didn’t managed to apply the force to the second object (The Sun).The movie which you can see above is a gif, cause […]

### Physics NO. 1 : The momentum of light

29Jun08

Well, everyone of us probably heard in high school (or earlier) that the photon has it’s own momentum. And I think that more then a half of us kept wondering then about it. Namely, without deep knowledge of Physics, such statements like “light have no rest mass”, or “light is an electromagnetic wave, but it […]

### Methods in Physics NO. 1 : Image Method

27Dec07

Suppose that we have a grounded sphere made from a conductor and an electron far from the sphere. Let the radius of the sphere be and the beginning speed of the electron be orientated on the line in distance of from the center of the sphere. The smallest distance between electron and the center of […]

### Problem NO. 1 : Law of the Adiabatic Process

25Dec07

Reading R. Resnick – D. Haliday thermodynamics, I’ve found something well known me although it’s making me wonder every single time when I think about it. It’s the derivation of the thermodynamics law that goes like this: From first law of thermodynamics , but in the adiabatic process we have and instead of we put […]

### When Superposition Rule Doesn’t Work?

27Oct07

Superposition is such an obvious rule in Physics that it’s worth telling when it doesn’t work. The rule breaks, when equatation of a wave is not longer linear. It happens when the altitudes are big enough to make the Hook’s Law fail ( ). Example: Shock waves after explosions which characteristic differs from a normal […]
