Ey, GlassDragon... tell me more about this mirror theory, please

i have a relating question... my friend was studying electrical when he figured out that computer engineering is better for him.. he says that EE requires a lot of complicated mathematical derivations and integrations... he told me that all the interesting stuff like programming and logical...

i'm so sorry i couldn't take place in such discussion because I'm not an advanced physics student, yet. but at least i got something to tell u, which is that Newton, as well as anybody publishes a theory, found the essential formula of any system including force. the whole process is...

a space shuttle... before u break off the Earth's atmoshpere try jumping off that thing... and feel the POWER -in case u won't be hit by a heart attack first-. nothing is really comin' up to my mind but springs... u can make a very big one and a small one... if ur askin' about qualities then...

let me tell u something omin, try to punch someone so hard on his shoulder-for example-, ofcourse u exert force there...u were asking like: where is the feedback force? well, don't u feel ur hands get hurt? that's the equal opposite power... sometimes that's unimaginable (if that's even a word)...

thank u people... i got it, but I'm going to make another sketch to correct those vectors, but i'll consider that vectors of forces start from the point of the centre mass of the body, if u know what i mean.. but i might be late because I'm very busy these days... so don't wait much... but i'll...

WELL, GUYS, I CAN'T BELIEVE I MADE IT... but i got to tell you doc that's how i studied it in books... i believe in that now that they r so odd but how should it be? in other words, please can u show me how could i draw them? after thati can rest in peace

well, after trying hard to analyze the forces the way u explained to me i think ur mistaken when u were saying that net force acting on (m) is (N - W) because the force (-W) is acting on earth mass (M) not (m), and so as the other net force formula... anyway i tried to figure it out with a...

it's not about what would calculate average V.. my point is why can't we use the formula i have given for no linear velocities..

thanx guys now i got it... i'm grateful! :)

if the normal force defined as the force that acts on an object when it touches the surface perpendicularly, wouldn't it be at the opposite direction of the Weight (W) as a vector and with the same absolute value.. so that the formula would be : F(n)= -mg if this formula is correct (which is...

well... if it's only expplained by derivation methods, as robphy did, then I'm satisfied because i haven't studied derivation yet! but if there is a logical (i mean more like physics not like mathematics) explannation then i'll wait for an answer... anyway thank u all very much :)

Hi, this is my first post ever published on such forums... anyway i liked this forum very much especially the classic physics category... And i'll be very happy if somebody answers my question.. i read once that average velocity can be calculated by this formula ONLY when it's LINEAR: V...
