SSteve4Physics replied to the thread Tension in a string connecting two blocks having equal and opposite velocities.The centre of mass is some point on the string. At this point, 2 forces act: - tension: 120 N towards the 3 kg mass; - tension: 120 N...

SSteve4Physics reacted to kuruman's post in the thread Tension in a string connecting two blocks having equal and opposite velocities with
Agree.
And what external entity is there to provide the centripetal acceleration to the center of mass? Please look at the figure in post #8. -
SSteve4Physics replied to the thread Tension in a string connecting two blocks having equal and opposite velocities.Yes. The system described consists of 2 masses connected by a string with no net external forces. So the CM has a constant velocity of...

SSteve4Physics replied to the thread Tension in a string connecting two blocks having equal and opposite velocities.It's not an assumption. Using the Post #1 diagram we see that the momentum of the 3 kg mass is 15 kgm/s in the -y direction and the...

SSteve4Physics replied to the thread Tension in a string connecting two blocks having equal and opposite velocities.The system's centre of mass (CoM) has some velocity. If you find this and transform the velocities to the CoM frame, the figures are...

Like.
There is a reason why Google AI and other LLMs are not acceptable sources here. Stop quoting them, stop wasting your time trying to... -
SSteve4Physics replied to the thread I What does equiprobable mean in the context of thermal motion?.I'd like to add this to what @jbriggs444 has said. No. You are wrong! Try working through the following carefully. Step-1...

SSteve4Physics reacted to jbriggs444's post in the thread I What does equiprobable mean in the context of thermal motion? with Like.
How is it possible? Why should it not be possible? Why the surprise? It is very difficult to respond to an open ended question like...

SSteve4Physics replied to the thread I What does equiprobable mean in the context of thermal motion?.@Mike_bb, can I throw this in... Suppose you have ten 6-sided dice, each marked with the values: -3, -2, -1, +1, +2, +3. You throw...

SSteve4Physics replied to the thread I What does equiprobable mean in the context of thermal motion?.@Mike_bb, I’m coming into this thread rather late but would like to add some random thoughts which might help. It looks like you are...

SSteve4Physics reacted to Charles Link's post in the thread I Lennard-Jones potential and interatomic distance with Like.
I could be wrong, but I think the first curve represents the potential energy that the electron sees as a function of position as it...

SSteve4Physics reacted to eneacasucci's post in the thread I Lennard-Jones potential and interatomic distance with Like.
This explanation is super informative and accurate, I cannot thank you enough for this. My notes were wrong and I was so confused about it.

SSteve4Physics replied to the thread I Lennard-Jones potential and interatomic distance.@eneacasucci, I'd like to add this to what @Charles Link has said. That's not what the graph shows. The graph shows the potential...

SSteve4Physics replied to the thread I Is this Lennard Jones potential image wrong on the Wikipedia Italian page?.I agree. It would appear that ##- \frac {\partial F}{\partial r}## should be ##- \frac{dU} {dr} ##, which is the force, ##F(r)##...

SSteve4Physics replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.Yes, but the equilibrium position is not relevant. It’s essential to realise that to find the minimum value of ##F##, we must consider...
