the force holding molecules near to each other in a droplet of oil is "dispersion forces" within the droplet between the molecules... what does that have to do with the force between nucleons?

hi guys, i have heard this recently...that the strong repulsive forces of protons in the nucleus is only held together by neutrons which acts as a glue. here is the problem...HOW does it act as a glue? could it possibly be the neutrons converting part of its mass into energy E=mc^2 and use...

oh ok i understand now! XD thx

i have a question... according to time dilation...as an object travels close to the speed of light, relative to antoher observer, the time goes slower in the moving object and it will appear to be "younger' if it was a person on the space travel... however, relative to the person on the...

Pe = Potential energy Ke = kinetic energy i want to clear up some confusion in me... firstly...it is true to say that potential energy transforms into kinetic energy as an object...correct? then the definition of an ORBIT is constantly falling around a planet, non-stop... therefore...

Hi guys...something does not seem right in physics... escape velocity is defined as the initial velocity required by a projectile to rise vertically and just escape the gravitational field of a planet and gravitational potential energy = 0 only at infinity displacement from planet (i.e...

simply incorrect... there is one thing "observed" to be faster than light (superluminal velocities), infact, MUCH faster than light, so fast that it traveled backwards in time. however it was proven to be wrong later on as the light passed through caesium gas, the components of light reversed...

my source is from a teacher at james ruse, therefore i cannot link you to him...

i see what you are getting at...but i personally do not believe in the big bang theory..although i have to study it in high school now... 1. you can never go back in time since in order to do that, you have to exceed speed of light...and that is already impossible according to E=mc^2 as when you...

this thread is about the 1 light year long pole question, the thread was closed... the question was " if there was a pole that is 1 light year long...person A at one side and person B at another" if person A pushes the pole, does person B see it instanteously... most people said that it...

WOOHOO! XD lol thanks...that clears it up alot:rofl:

i was wondering the other way to calculate torque as it is calculated by Fd, F=force and d= distance from pivot. my question is... originally, torque is calculated by extending the line of force until it is perpendicular to the pivot. then that distance X force is the value of torque. i was...
