Hello, i am reading on the Bohr Model. There are some parts i just do not understand.
in classical mechanics, an object, such as an electron, revolving ina circle may assume an infinite number of values for its radius and velocity. Why is this?
Therefore the angular momentum (L= mvr) (? m=mass v=velocity r=radius ?) and the kinetic energy (KE= mv^2/2pi) (? m=mass v=velocity 2pi= something to do with a cirlce ?). again i don't understand why this is.
Bohr then goes to add Planck's quantum theory into his model. This sets conditions on the value of the angular momentum. the angular momentum is quantized according to the following equation: angular momentum = nh/2pi
n= quantum number that could be any positive integer. h is Plancks constant. I am not sure what 2pi is for.
if anyone could please explain these passages to me it would greatly help in my studies. thank you.
