If i consider two steel balls of the same mass; one at rest, other moving at some speed and colliding with the second one:
## m_A = 0.01 kg; V_A = 10 m/s; r_A = 6.68 mm ##
## m_B = m_A = 0.01 kg; V_B = 0 m/s; r_B = r_A = 6.68 mm ##
Kinetic energy travels at speed of sound through stainless st...
I am not arguing that the change can't be calculated. I am asking how two compare the magnitudes of the forces in the two cases i have described in the original post. It's clear that the impulse in the second case is greater than the first. If i have to talk in terms of the force that resulted...
Yes, yes i did have an inkling that this assumption mustn't be included to have the right picture of the situation.
So if we are to include the elastic set up for the two colliding objects now; thinking about spring-like forces, then how does adding more mass change the 'spring-coefficient', so...
Exactly. That should be the property of the material and i am considering that both A and B have the same make in both cases. But where i am failing is how to quantify that inertial resistance, that increase in average force, in terms of the normal force. How do i explain this increment as a...
I know that the forces involved in each collision are equal and opposite, from Newton's 3rd Law.
Question is whether the force on ball A has the same magnitude in each case as well. My reasoning says that it's not. What i want is to improve upon that reasoning if it's right or otherwise, get a...
Hi! I am having a little trouble with a question asked by a colleague.
There’s a ball B with a certain mass M, at rest. A small ball A of mass m is moving with speed v toward M.
If m=M, and the collision is perfectly elastic and the two objects perfectly rigid, than we know that A would come...
First of all, thank you for your quick replies. They are very helpful.
In the effort to hammer my understanding of this concept down to the last bit:
two similar frequencies will give us a beat whose frequency will be the average of the two; it's amplitude will vary at a rate of half the...
Thank you for the reply. Just to be clear, the reason we can't say that the time periods of the two combining SHMs that are giving us a beat here, are commensurable because the amplitude is not constant? It's being modulated at 2 Hz and therefore we can't use T = n1T1 = n2T2 here?
Hi. I have been reading about the superposition of simple harmonic vibrations of different frequencies and what entails to make the their combination periodic. This is quoted from the book Vibrations and Waves by A.P. French: "The condition for any true periodicity in the combined motion is that...
