What is the acceleration of a particle orbiting around a nucleus?

AI Thread Summary
The acceleration of a particle orbiting around a nucleus can be expressed as a = v^2/r, indicating that it experiences radial acceleration. In the context of electron orbitals, electrons do not exhibit circular motion and are described by probability density functions rather than definite paths. The discussion highlights a distinction between classical particle motion and quantum mechanics, where traditional acceleration concepts may not apply. There is some confusion regarding specific equations related to acceleration, particularly in the context of K-12 education. Understanding these differences is crucial for accurately discussing particle behavior in atomic structures.

What is the acceleration of a particle orbiting around a nucleus?

v/(4(pi)) = a ?

I cannot find this info... Will you help me?

r = r0

If it is a uniform motion it will have radial acceleration of

a_r= \frac{v^2}{r}

wait... is it really?

If you really mean a particle orbitting, then it is a=v^2/r.

If you're talking about electron orbitals, not orbits, the electrons are not accelerating. The elecrons do not whip around in a circle around a nucleus. The orbital is the space defined by the probability density function of the electron.

I agree with Njorl
The Que said particle, i.e with definite coordinated and since the forum is in K-12, i didn't delved into probability theory

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
