hello! here's my problem: Newtons second law implies: F=m*dv/dt+v*dm/dt first part of the equation says if I act on the object then it's reaction will be acceleration, but the second part says if act on the object it will cause changes in object's mass. In case where I'm dealing with non...

Thanks a lot! Now I am happy again!

hi, I just heard about particles traveling faster than speed of light and somthing about cerenkov radiation. Is it possible for some subatomical particles to overcome speed of light? if yes, doesn't it contradicts einsteins relativity? I'm pretty confused please help.

Thank you that helped.

we all know that there is upper limit for speed that is speed of light, but is there a lower limit, I mean is there quanta for speed.
