Gavran's latest activity

You ask about the difference between thermal energy and mechanical energy. Both are two different forms of kinetic energy, which is the...

Subatomic particles present wave-like behavior that is real and measurable but is not classical particle behavior. It's not just a...

It’s better, thanks. You can’t lift halfway, then start again to go higher; the car must be lowered before raising again, to allow the...

Unfortunately the OP is applying his own private definition of "equilibrium" (basically "any arbitrarily chosen reference") and thus...

You are wrong. For instance, in the case of a moving particle with a constant velocity, a position change of a moving particle cannot be...

Very similar to post #6. $$ a^0=a^{x-x}=\frac{a^x}{a^x}=1 $$

In my opinion, your definition is correct, but it is incomplete. I agree with @kuruman (post #5) that a wave in classical physics does...

So I googled "What is a wave?" and this is what I got. If you go by this more complete AI overview and not by what Wikipedia says, your...

"While waves are ubiquitous features of physical systems, no single definition adequately describes the topic." (from Wikipedia)

Note: @Gavran 's method (post 15 above) needs a second power form to take the discriminant. @pasmith 's method works in the general...

Since there is no energy loss to the environment in this case, the initial thermal energy of each mass of liquid becomes the final...

Clearly, the equation ## 4x^5u''+12x^2u'-4u=0 ## is not a Cauchy–Euler equation, and it cannot be solved by the standard method, which...

I would like to give a big thank you to @anuttarasammyak , @pasmith , @Gavran , and @DaveE for their inputs to this thread. I really...
