Thank you for your time and effort. I have this big question bothering me, I would think that on the explosion there would be forces involved (those of the explosion) how can moment be conserved in this case?

@yoprofmatt 4 жыл бұрын

Miguel, Newton's 3rd law says that for every force there is an equal and opposite force. So those explosive forces pushing particle 1 to the right are also pushing particle 2 to the left. Newton's 3rd leads directly to conservation of momentum. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A

Ghost Reaper724, Yes, momentum is always conserved IF the system is isolated. On Earth, we always have gravity, so your experiment is not really an isolated system.

Where would you substract energy loss? Would you calculate it as a whole at the moment of the explosion and substract it from Pi? Then calculate it for each of P1, P2 and P3 and decrease respective V depending on time?

In the calculation of the Pfx, why would you not be using absolute values ? Is the final P in the x direction not the absolute sum of the parts ? To have m1v1 as negative seems to suggest a loss in overall P thus making the statement Pix = Pfx untrue. Thank you Prof. Matt.

@yoprofmatt 4 жыл бұрын

Ciscoho, Typically we don't use absolute value bars in physics. Too time consuming. Generally all variable are thought of as positive. If something needs to be negative, we put that out in front.

It all makes sense except for one thing. Doesn't the explotion add more energy to the system, thus altering V1, V2 and V3?

@yoprofmatt 7 жыл бұрын

Excellent question. The explosion certainly increases the SPEED of the individual particles, meaning the energy of the explosion is transferred to the kinetic energy of the particles. But momentum is concerned with VELOCITY, which means the direction matters. The explosion cannot change the momentum of the system. Perhaps one way to think of it is this: if a stationary object explodes into two equal parts and one part is going to the right at v, what happens to the other particle? Reply back and let me know what you think. Cheers, Dr. A

Yan, Good question. Conservation of momentum always holds, so even though the particles shoot our at high velocity, the total momentum (a vector quantity) has to be conserved.
